Suspect claims he was checking security

ANASET, Sweden, July 15 (UPI) -- A man who took $3,350 in cash from a Swedish bank and subsequently returned the money claims he was just testing the bank's security.

Police in Anaset said the man walked into an unlocked safe at Swedbank on Oct. 11, 2007, and walked off with the cash, but the money reappeared in the bank's mailbox the following weekend with a note, the Swedish news agency TT reported Tuesday.

"I am sorry that I took the money. I feel very ashamed," the note read.

Investigators said they tracked down the suspect after he was caught on security cameras entering and leaving the vault and his fingerprints were found on the note with the returned cash.

Police said the man initially denied the crime, but later admitted to taking and then returning the money. However, his story changed from that indicated by the note.

The suspect told officers he saw the unlocked safe and felt an impulse to check the bank's security. He said he never intended to keep the money and denied writing the apology note.

The man has been arrested on suspicion of theft.
