Two armed robberies at Catonsville area ATMs last weekend may be linked to two other similar incidents in June, according to Baltimore County Police.
Police spokeswoman Cpl. Cathy Batton said at 4 p.m. on Tuesday that police would not confirm that the four incidents were related, but they are "investigating them as being connected incidents."
In the latest incident, a 23-year-old driver and his 19-year-old passenger, both Baltimore City residents, had pulled up to the drive-through ATM at Wells Fargo bank at 582 Frederick Road on July 22, when a green Nissan Altima pulled up behind them, police said.
A man got out of the Nissan wearing a black ski mask and black hoodie and walked up to the car where he pointed a handgun at the driver's face, police said.
The man with the gun demanded the driver take the keys out of the ignition and give him the money he had withdrawn from the bank machine, his bank card and PIN number, police said.
After telling the driver to leave, the man with the gun made a transaction, police said.
The man is described as black with a medium build, between the ages of 23 and 35 and about 5-foot-10.
At 10 p.m. on July 21, a woman had used the drive-through Bank of America ATM at 5700 Baltimore National Pike when a man with a black face covering came between her and the car, displayed a gun and demanded money, Batton said.
After the man took the money and fled, the woman drove away, Batton said.
On June 17, a man armed with a handgun wearing all black clothing and a ski mask held up two people in separate incidents who were using area ATMs.
At 9:40 p.m. that day, a man came up behind a woman who was using the ATM at the M & T Bank branch at 4656 Wilkens Ave., pointed a revolver at her and demanded cash, police said.
After the woman said she had no money, the robber fled.
About a half hour later, at an ATM about 3.5 miles away, a man withdrawing money from an ATM at M & T Bank branch at 5642 Baltimore National Pike in Catonsville was approached by an armed man wearing all black and a ski mask who demanded cash, police said.
After getting the cash, the robber fled in a white sedan, police said.
