Two of Roger Penske’s sons were arrested by police, for allegedly breaking into the Nantucket Yacht Club and assaulting two women.

Billionaire Roger Penske started racing in 1958; he later built the truck leasing business which bears his name, and owns numerous car dealerships along with Indy and NASCAR teams. The sons who were arrested are Jay Penske, CEO of digital media company PMC and owner of Dragon Racing, and Mark Penske, 35.

Two women contacted the police and said they had been assaulted by two men in the parking lot; they identified the men as the Penske brothers. The assault was defined as urinating on one of the woman’s boots, then grabbing her and pushing her.

According to the police, Jay Penske was found trying to run away from the club, and Mark Penske was at the employee apartment; he had fallen down the staircase.

The women did not press charges. The brothers were jailed overnight, and were arraigned in the morning on charges of breaking and entering with intent to commit a misdemeanor. (Via Yahoo Sports / thanks, MoparBob.)
