A Mexican man bit a Border Patrol agent Monday while attempting to evade arrest, according to the federal criminal complaint against him.

At about 3 a.m. Monday, police called Border Patrol to the intersection of Farm-to-Market Road 495 and Washington Street in Mission.

Officers told the Border Patrol agent who responded that police stopped a car for suspicious activity, according to the criminal complaint. Police determined the driver was a citizen, but two passengers weren’t legally present in the United States.

When the Border Patrol agent attempted to arrest one of the passengers — Dennis Rafael Perez-Perez, a 24-year-old Mexican citizen — he started running.

The agent chased Perez and attempted to detain him.

Perez bit the Border Patrol agent’s left index finger, according to the criminal complaint.

FBI agents invested the incident and charged Perez with interfering with a Border Patrol agent.

Court records don’t list an attorney for Perez, who remains in federal custody.
