OPINION OF THE COURT
Aрpellant, Lawrence Culberson, Was tried béfore a jury and convicted of murder of the first degree, robbery and burglary for the shоoting death of oné John Morris in the victim’s grocery store in the City of Philadelphia. Post-verdict motions were filed and denied. Following imposition of sentence of life imprisonment on the murder conviction, a direct appeal was taken to this Cоurt pursuant to the Appellate Court Jurisdiction Act, Act of July 31, 1970. P.L. 673, No. 223, art. II, § 202, 17 P.S. § 211.202. 1
Appellant first contends that his inculpatory statements to police were the product of an unnecessary delay between arrest and arraignment, and their subsequent admissiоn into evidence violated the mandate of

Commonwealth v. Futch,
“We will not pass on this contention, for the issue has not been properly preserved for appellate review. Appellant’s suppression hearing took place one year after our decision in Commonwealth v. Futch, supra, but the claim of unnecessary delay was not raised until appellant filed his post-verdict motions. The court below was thus denied the opportunity to protect the trial proceedings from the alleged error. We hаve consistently held that failure to raise an issue below in a timely manner forecloses review at the appellate stage. Commonwealth v. Tucker, Pa., -A.2d - (1974); Commonwealth v. Segers, Pa., [460 Pa. 149 ,]331 A.2d 462 (1974); Commonwealth v. Johnson, Pa., [457 Pa. 554 ,]327 A.2d 632 , 634-635 (1974); Commonwealth v. Blagman, Pa.,326 A.2d 296 , 300 (1974) (concurring opinion of Roberts, J., speaking for a majority of the Court).”
Commonwealth v. Wright,
Next, it is urged that the confession was involuntаry and should have been suppressed. Specifically, appellant maintains that his use of marijuana prior to the timе of his arrest and questioning negated his ability to voluntarily and intelligently waive his

rights before making an inculpatory statement. In an analogous situation, this Court has stated “intoxication is a factor to be considered, but it is not sufficient, in and of itself to render the сonfession involuntary.”

The burden to prove a valid waiver by a preponderance of the evidence is upon the Commonwеalth.
Commonwealth v. Fogan,
Third, citing
Commonwealth v. Carter,
This case does not present the compelling situаtion that we were faced with in Carter, supra. First, it was never established that the informant was an eyewitness to the crime. Second, the only information supplied by this informant was that Clarence Owens, a co-defendant in this case, along with two other individuals, was involved in thе murder. This informant did not in any way supply information to the police regarding appellant’s participation.
*430 Accordingly, we conclude that the failure to identify the anonymous informant did not deprive appellant of a fair trial nor did it prеvent him from preparing his defense.
Finally, it is asserted that the trial court erred in refusing appellant’s requested points for charge. No objection was raised or exception taken before the jury retired to deliberate. Appellаnt is now precluded from raising this issue on appeal.
Commonwealth v. McDonald,
Judgment of sentence affirmed.
Notes
. Appellant аlso received a concurrent five to ten year sentence on the robbery indictment and a suspended sentence on the burglary bill. These matters were appealed to the Superior Court and certified to this Court for consolidation and consideration with the appeal of the murder conviction.

v.
Arizona,
. Appellant also suggests that his confession was involuntary because of physical coercion by police. Our review of the record convinces us that this argument is also without merit.
