SAN ANTONIO – A man who was shocked with a stun gun while he evaded a deputy showed up at the Bexar County Sheriff’s Office with prongs from the weapon still in his back, according to deputies.
Robert Pena, 39, was arrested Friday morning after he went to the station to update paperwork regarding his sex offender registration, BCSO said.
Pena was wanted by BCSO following an incident on Thursday morning in the 6800 block of Blue Lake Drive.
In that incident, a deputy answered a call about a suspicious person and saw Pena exit a vehicle. The deputy told Pena to stay in the vehicle, but Pena ignored him, BCSO said.
A report indicated that the man was doing drugs in his car as the deputy approached him, then put up a fight when he tried to arrest him.
At some point in the struggle, Pena hit the deputy in the back of the head, causing a cut, BCSO said.
The deputy shocked him with a Taser but somehow, the suspect was able to break the wires on the stun gun, run to his car, and drive off.
Because of heavy morning traffic and school zones in the area, BCSO did not pursue him. However, deputies were able to identify him.
On Friday morning, Pena called the BCSO Sex Offender Registry Team to tell them he was headed to Colorado and needed to update law enforcement officers as a condition of his sex offender registration.
The team told Pena to show up in person at the sheriff’s office to register. He showed up at 8:30 a.m. and was then placed under arrest.
Record show he was charged with assault on a peace officer and evading arrest.
Because he still had Taser prongs in his back, he received medical attention shortly after the arrest.
He has been a registered sex offender in Texas since 2018, records with the Texas Department of Public Safety show.
