Police located Brandon Bennett, 24, of Lansdowne and Jamar Gregory, 21, of Tresckow, PA, in the bank. Bennett was an employee with Premier Cleaning Services, the company that had the contract with the bank, according to Michael J. Chitwood, Upper Darby superintendent of police.
Bennett told police he found the combination on a piece of paper about a month prior. Chitwood said he did not know where the combination was found.
Bennett listed the help of Gregory to pull off the heist, Chitwood said.
The vault contained about $100,000.
When the two began to try the vault's combination, a security camera was activated and so was an alarm, he said.
"Fortunately the bank has security that sends a signal there is something wrong or else they'd be out $100,000," said Chitwood.
The two are charged with theft, receiving stolen property and related crimes. They were both remanded to the Delaware County jail after failing to post bail, according to court records.
"Had they made a big score they wouldn't have been into work on Monday," Chitwood said.
