Mayor of College Park, Md., Resigns Over Child Abuse Imagery Charges

Court records indicate that the account was on the social media app Kik.

Prince George’s County Police investigators determined that videos and an image had been uploaded to the account in January, and that the account belonged to Mr. Wojahn, the police said.

On Tuesday, detectives served a search warrant at Mr. Wojahn’s home, where they seized cellphones, a storage device, a tablet and a computer, the police said.

News of Mr. Wojahn’s arrest prompted shock and dismay in College Park.

“The alleged criminal behavior is reprehensible,” Thomas E. Dernoga, the chair of the Prince George’s County Council, and Eric C. Olson, a council member who represents College Park, said in a joint statement on Thursday.

“These are extremely serious charges that represent a violation of the public trust extended by the residents of College Park, and the duties as an elected official,” Mr. Dernoga and Mr. Olson said. “This is a sad day for all of us.”

Mr. Wojahn, a Democrat who grew up in Wisconsin, received his law degree from Georgetown University Law Center in 2002, and ran for mayor in 2015 “to help College Park realize its unfulfilled promise of becoming a top-tier college town,” according to his biography on the city’s website.

In addition to serving as mayor, Mr. Wojahn worked as the director of government relations for the Rails-to-Trails Conservancy, a nonprofit group that seeks to convert unused rail corridors into trails and to expand bicycle and pedestrian routes, the biography states.

Rails-to-Trails Conservancy said in a statement on Thursday that it had immediately placed Mr. Wojahn on leave.
