An indecent-exposure case that led to an Anchorage car chase this week ended with the first arrest made by a newly formed local police unit.

Police spokesman MJ Thim said the events which led to 36-year-old Tyshaun Gray’s arrest began downtown at about 7 p.m. Wednesday.

“We got a report of an indecent exposure on the 700 block of D Street,” Thim said. “It was an adult male sitting in a 2007 Chevy Silverado masturbating, and he was trying to get the attention of others.”

A woman who saw Gray called 911, Thim said. Arriving officers learned the Silverado had recently been stolen in Ship Creek; during an ensuing chase, the Silverado was seen driving recklessly in Fairview and near the Northway Mall.

“One of the locations that the suspect had driven through was in the area of 12th (Avenue) and Fairbanks (Street); the suspect had run over a stop sign,” Thim said. “At some point the suspect was driving up on sidewalks trying to elude us – he was driving so recklessly that it caused a public-safety threat.”

Members of APD’s Investigative Support Unit, eight officers and a sergeant on hand starting this month to support new cases, were called in to help apprehend Gray. Thim said officers were able to box in the Silverado near the 200 block of Alaska Place, where Gray tried to run but was soon taken into custody.

Gray was arrested on charges including indecent exposure, vehicle theft and failure to stop at the direction of an officer. The owner of the Silverado, which was damaged during the chase, was notified of its recovery.
