Dallas police said a man died Monday evening after an officer used a Taser in an attempt to subdue him.

According to investigators, 25-year-old Ross Anthony was "exhibiting erratic behavior" when he was found inside a parked vehicle in the 5400 block of Jim Miller Road around 7:30 p.m.

After officers ordered the man to exit the vehicle, there was a struggle, and extra help was requested.

Police said Officer Paul Kessenich deployed his stun gun to subdue the suspect.

"Mr Anthony began to show signs of medical distress shortly after he was handcuffed," a police statement said.

Anthony was taken to Baylor University Medical Center, where he was pronounced dead. The results of an autopsy have not yet been released.

Kessenich and three other officers involved in the incident were placed on routine administrative leave pending the outcome of an inquiry by the department's Special Investigations Unit.
