Gregory Baskin sued the City of Des Plaines and Officer Bruce Sotirakis under 42 U.S.C. § 1983. Mr. Baskin alleges that Officer Sotirakis, a member of the Des Plaines Police Department, violated his constitutional *703 rights during a police stop in January 1995. In the district court, both defendants moved to dismiss Mr. Baskin’s second amended complaint. See Fed.R.Civ.P. 12(b)(6). On May 7, 1997, the district court- granted the defendants’ motions. For the reasons set forth in the following opinion, we affirm the judgment of the district court.
I
BACKGROUND
On November 22, 1996, Mr. Baskin filed a complaint under 42 U.S.C. § 1983, alleging that the City of Des Plaines and unknown police officers violated his constitutional rights during a traffic stop on January 26, 1995. On February 10, 1997, Mr. Baskin filed an amended complaint which was essentially identical to his first complaint and which continued to designate as defendants the City of Des Plaines and unknown police officers. Finally, on March 13, 1997, Mr. Baskin filed ’ a second amended complaint. In that complaint, Mr. Baskin once again named the City of Des Plaines as a defendant and added a specifically identified individual defendant, Officer Bruce Sotirakis.
In his second amended complaint, Mr. l?askin alleged that on January 26, 1995, at 2:15 p.m., Officer Sotirakis pulled him over for a traffic stop. Mr. Baskin alleged that, during the course of this stop, Officer Soti-rakis subjected him to arbitrary and threatening conduct, assault and excessive force. In addition, he contends that Officer Sotirak-is conducted an unreasonable search of his vehicle in violation of the Fourth .Amendment. Mr. Baskin further alleges that the City of Des Plaines ratified the conduct of Officer Sotirakis by refusing to accept any complaint from him and by failing to take any disciplinary action against Officer Soti-rakis.
On April 9, 1997, Officer Sotirakis filed a motion to dismiss based on Mr. Baskin’s failure to name him as a defendant prior to the expiration of the statute of limitations. He contended that the relation back provision of Rule 15(e)(3) of the Federal Rules of Civil Procedure was inapplicable. Two weeks later, the City of Des Plaines filed its motion to dismiss based on Mr. Baskin’s failure to plead properly a § 1983 action against a municipal defendant. On May 7, 1997, the district court granted both motions. Mr. Baskin appeals that ruling to this court.

DISCUSSION
This case is before the court on appeal of the district court’s grant of judgment on the pleadings.
See
Fed.R.Civ.P. 12(b)(6). In reviewing the district court’s ruling, therefore, we must take the allegations of the pleadings as true.
See Conley v. Gibson,
A.
We turn first to Officer Sotirakis’ motion to dismiss. In that motion, Officer Sotirakis sought dismissal of Mr. Baskin’s second amended complaint because it was filed after the expiration of the statute of limitations and it does not relate back to the date of Mr. Baskin’s original complaint under Rule 15(c)(3) of the Federal Rules of Civil Procedure. In § 1983 actions, the federal courts adopt the forum state’s statute of limitations for personal injury claims.
See Wilson v. Garcia,
*704
It has long- been the law in this circuit that Rule 15(c)(3) permits an amendment to relate back to the original complaint only “ ‘where there has been an error made concerning the identity of'the proper party and where that party is chargeable with knowledge of the mistake.’ ”
Worthington v. Wilson, 8
F.3d 1253, 1256 (7th Cir.1993) (quoting
Wood v. Worachek,
In this case, Mr. Baskin did not make a mistake concerning Officer Sotirakis’ identity when he filed his original complaint; he simply did not know the identity of the police officer who pulled him over on January 26, 1995. Accordingly, when Mr. Baskin later amended his complaint to name Officer Soti-rakis as a defendant, that amendment did not relate back to the filing of his original complaint. Thus, because Mr. Baskin did not amend his complaint to name Officer Sotirak-is as a defendant until after the statute of limitations had expired, the district court properly dismissed his complaint against Officer Sotirakis as untimely. 1
B.
We turn next to the motion to dismiss filed by the City of Des Plaines (“the City”). In its motion, the City sought dismissal of Mr. Baskin’s second amended complaint on the ground that Mr. Baskin failed to plead sufficient facts to hold the City liable under § 1983. Although a municipality is subject to suit under § 1983, respondeat superior liability will not suffice to impose § 1983 liability on the City.
See Monell v. New York City Dep’t of Soc. Servs.,
In this case, Mr. Baskin clearly does not allege any facts supporting the first two instances in which a municipality may be held hable under § 1983. His second amended complaint does not allege that Officer Sotirakis acted pursuant to an express policy of the City of Des Plaines. Moreover, in his response to the City’s motion to dismiss, Mr. Baskin acknowledges that he “is unable to allege that Sotirakis’s actions were part of a pattern or series of inappropriate conduct.” R.21 at 1. Accordingly, in order to survive the City’s motion to dismiss, Mr. Baskin’s second amended complaint must contain allegations sufficient to support the conclusion that his “constitutional injury was caused by an individual with final policymaking authority.”
Baxter,
Paragraph 11 of Mr. Baskin’s second amended complaint reads:
11. When plaintiff subsequently attempted to file a complaint, ... the City refused to accept any complaint or to take any action against Sotirakis. The City’s inaction encouraged Sotirakis and the other officers to continue in their unreasonable, arbitrary and threatening conduct, thereby establishing a policy of allowing its officers to violate an individual’s civil rights without fear of being disciplined.
R.12 at para. 11. Even when taken as true and construed liberally, this allegation does not set forth a situation that would justify the imposition of liability against the City under § 1983. Mr. Baskin does not allege that Officer Sotirakis himself was a policymaker; nor does he allege that a city official with final policymaking authority acknowledged Officer Sotirakis’ conduct and approved of it. As discussed above, it is well settled that a plaintiff seeking to establish a § 1983 claim against a municipality based on a “ratification” theory must allege that a municipal official with final policymaking authority approved the subordinate’s decision and the basis for it.
See Kernats,
Conclusion
For the reasons set forth in the foregoing opinion, we affirm the judgment of the district court.
AFFIRMED.
Notes
. In urging us to reverse the district court’s dismissal of his complaint, Mr. Baskin relies heavily on
Donald v. Cook County Sheriffs Department,
The situation presented by this case is clearly different from that presented in Donald. In that case, the plaintiff satisfied the "mistake” requirement of Rule 15(c)(3) — he filed his original complaint under the mistaken impression that he could effectively sue the individual defendants by naming the Sheriff's Department. See id. at 560. By contrast, in this case, Mr. Baskin simply did not know the name of the proper defendant. Furthermore, in Donald, the plaintiff was a pro se plaintiff and, as such, should have been given special consideration by the district court. See id. at 555. In this case, Mr. Baskin was represented by counsel and thus was entitled to no such special consideration. Instead, Mr. Baskin "must bear the consequences of his ... procedural lapses and mistakes in pleading, even if the result is the denial of relief which is otherwise well-deserved." Id. at 554.
