COPPELL -- Police have arrested a man they believe robbed a student outside Coppell High School.

The victim told officers he was in the school parking lot just before 6:30 p.m. Tuesday when a man pulled up in a newer silver Nissan Sentra and asked him questions. He then pulled out a handgun and demanded the student's cell phone and wallet. The student complied and the suspect drove off.

He was described as Hispanic with a goatee, and was wearing a dark shirt, possibly Nike brand with writing on it.

Just after 7 p.m. Wednesday, a resident in the 100 block of Hartford Circle called police about "suspicious activity" and said a parked vehicle may have been involved in the robbery of the student from the day before.

When officers arrived and made contact with the driver, they say he became "uncooperative" and wouldn't get out when asked.

"At one point, the individual displayed a handgun although he did not point it at the officers. The driver became erratic and showed signs of drug use," police said.

The Coppell PD SWAT team was called and a perimeter was set around the vehicle. After about an hour, the driver surrendered. He's currently a "person of interest" in the robbery at the high school, and was arrested on a warrant for a different aggravated robbery.

He has not been identified.
