Plano police have arrested a man they say carjacked an off-duty Dallas officer on Friday, getting away with her gun and badge inside the vehicle.

Dominic Mignogna is being held on aggravated robbery charges. Richardson police noticed the stolen car outside his home, then called in their Plano colleagues.

Investigators found Mignogna inside and arrested him around 2 a.m. Saturday. They also recovered the Dallas officer's weapon.

The car was taken as the Dallas officer was refueling early Friday morning at a gas station in the 600 block of East Plano Parkway.
