Police were still searching Friday night for a man who robbed a South Portland bank that morning.

Officers say the Key Bank on 445 Gorham Road was robbed by a lone male suspect displaying a note, demanding cash and threatening staff with an explosive device.

No one was harmed and no weapon was displayed, but the robber still left with an undisclosed amount of cash in a black Chevrolet Suburban, police said.

They have recovered the car but not the suspect, whom police described Friday as a white man wearing a black jacket, a black mask, a beanie-style cap and sunglasses.

Police found the car at a parking lot about a mile from the bank, on 75 John Roberts Road. They say the vehicle was likely stolen. The car has been impounded for evidence processing.

Investigators continue to pursue several leads, they said. They had help Friday from the Portland Police Department Hazardous Device Unit and Maine State Police.

KeyBank in Maine spokesperson Karen Crane said Friday evening she couldn’t comment on details of the robbery for security reasons.

“We are happy to know all clients and employees are safe,” Crane wrote in an email.

South Portland Police say that if anyone has information about the suspect, they should contact the department at 799-5511 and ask for Detective Stearns (extension 7212), Detective Lt. Todd (extension 7448), or leave an anonymous tip by calling 347-4100.
