Las Vegas Metropolitan Police arrested New Orleans Saints running back Alvin Kamara on a battery charge Sunday night following the Pro Bowl, but revealed that they and the NFL knew Kamara was a suspect hours before the Pro Bowl began.
Assistant Sheriff John McGrath told the Nevada Current on Monday that they identified Kamara as a suspect on Sunday morning, but in order to gain his cooperation so they could find out the identities of the others involved in the incident, police opted to wait until after the Pro Bowl to interview him.
