Police are hoping the public can help identify a man suspected of robbing five customers in separate incidents at a Lowell bank ATM since January, Lowell police said.
The suspect has surprised customers using the ATM at the Washington Street Savings Bank on Middlesex and Central streets, Lowell Police Department Deputy Superintendent Arthur Ryan said.
“Our concern is that the robberies seem to escalate in violence,” Ryan said. In the last two robberies, including the most recent on Sunday, the suspect has brandished a knife, though none of the victims were injured. Previously, the suspect got physical, pushing the victims around, but did not strike them, Ryan said.
The suspect is described as 20 to 30 years old, 5-foot-6, with a medium build.
All five robberies happened when the bank was closed. Initially, the suspect got into the ATM vestibule and surprised customers using the machine, Ryan said, until the bank upped its security and changed locks. In more recent attacks, the suspect has lurked outside.
Police believe the suspect is still in the area and has only targeted this bank location.
“He seems to be comfortable with this spot,” Ryan said.
The police and the bank are offering a $2,000 reward for information on the suspect’s identity. Anyone with information is urged to contact Lowell police at 978-937-3200. To remain anonymous, call 978-459-TIPS (8477) or text 847411.
