An assault suspect was shot by a U.S. Customs and Border Protection officer at the Otay Mesa Port of Entry Wednesday after allegedly advancing toward an officer while holding a screwdriver and ignoring commands to drop the weapon.

No trucks were being allowed to cross at the port. It was unclear when the closure began or what prompted the decision.

CBP officers seized over $1 million worth of cocaine hidden in a tractor-trailer at Otay Mesa Commercial Facility.
