Portland police have not yet made an arrest in the robbery of a KeyBank branch in North Deering on Friday, a police spokesman said Saturday evening.

Police are searching for a man with a semi-automatic handgun who robbed the KeyBank branch on Auburn Street about 2 p.m. Friday.

Lt. Robert Martin said police did not have any updates about the robbery to release to the public on Saturday.

Police shut down parts of three streets Friday night in East Deering as they searched for the bank robber. Police would not say how much money was taken.

The man, who was wearing a blue hooded sweatshirt, sunglasses and a black wig, was described by witnesses as white, thin and having a deep voice.

He fled the bank on foot. He was last seen on Brook Road, police said Friday in a news release.

Maine State Police, Falmouth police and the FBI joined Portland police in the manhunt that shut down the neighborhood near Presumpscot Street and Ocean Avenue for several hours. The area was reopened just after 9 p.m. Friday.
