CLEVELAND, Ohio -- An Akron police officer has been charged after police said he attacked a man outside a Playhouse Square hotel after a police fundraiser event.

Adam Campbell, 28, of Uniontown, is charged with felonious assault, according to Cleveland Municipal Court records. The victim in the attack is listed as Steven Crupp, 31, who was jumped by three men outside the Wyndham Hotel March 29, after a Cleveland Police Scholarship Fund black-tie fundraiser.

Campbell was hired as an Akron police officer on Nov. 3, department spokesman Lt. Rick Edwards said. Campbell has been placed on unpaid administrative leave. The department's internal affairs unit is also investigating the incident, Edwards said.

Reached by phone Monday, Crupp said he did not know Campbell.

Crupp met two women at the Blue Bar at the Wyndham March 29 after he went to the NCAA Elite 8 game.

Also at the hotel that night was the Cleveland Police Scholarship Fund's annual black-tie optional charity auction. The $75-per plate gala was open to anyone willing to donate to the scholarship fund and was not exclusively attended by police officers.

Crupp said he was jumped by a man wearing a tuxedo in front of the hotel just after midnight. Cleveland police Monday identified that man as Campbell and obtained a warrant for his arrest, according to a sworn affidavit.

Crupp said two other men helped hold him down. He was left with six broken ribs, a stress fracture in his hip and an abscess in his tooth after the attack.

A valet manager on duty at the hotel that night said he saw a group of people quickly shepherd the attacker into a taxi cab, which drove away. The valet manager, Kenneth Hillner, told Northeast Ohio Media Group that the attacker appeared "heavily intoxicated."

The hotel's security cameras caught the incident. Northeast Ohio Media Group requested a copy of the footage Wednesday. Cleveland police spokesman Sgt. Ali Pillow said the department had to subpoena the Wyndham to get a copy of the footage, which it first obtained on Friday.

Crupp's attorney, Ian Friedman said Crupp is "extremely grateful" to Cleveland police for "handling the case as quickly and seriously as they did."

Friedman said he hoped detectives would soon be identify the other two suspects.
