AUSTIN (KXAN) — A man who tried to set pumps at a southeast Austin gas station on fire might have been under the influence of K2, police say.

The Austin Fire Department said they were called out to the Shell gas station at 6301 East Riverside Drive around 3:30 a.m. Wednesday. The caller originally said the suspect was trying to start a fire but when crews arrived, there wasn’t a fire.

The suspect, identified as Christopher Kempf, 45, was arrested and charged with deadly conduct.

Over the past few days, Austin-Travis County EMS has responded to an increase of K2-related calls in the downtown area. On Sunday, the agency said it evaluated nine patients for possible K2 overdoses.
