An Indiana factory worker repeatedly bashed a colleague over the head with a hammer then calmly walked out, telling a colleague, 'S--- happens," according to a report.

Austin Hahn, 27, allegedly strolled over to his friend and bludgeoned him from behind with a tinner hammer before 7:30 a.m. on Aug. 20 at the Bright Sheet Metal Co. in Indianapolis, court records show.

Witnesses said Hahn had used the sharp side of the implement to strike the victim at least six times, according to an arrest report obtained by FOX59.

He then left the warehouse and "calmly" tossed the hammer in the trash in front of an employee who was outside and unaware of the altercation.

As Hahn walked by the co-worker, he allegedly paused, patted him on the chest and said, "S--- happens," according to the local outlet.

Hahn's colleagues told police that he and the victim were "the best of friends" before a dispute occurred several weeks ago.

But Hahn had apologized, and they thought the bad feeling had been quelled.

Hahn's mother called the Anderson Police Department later that morning, and he was arrested.
