A shoplifting suspect who police say was armed with a knife barricaded himself inside a fitting room at a JCPenney in Maryland on Wednesday, prompting authorities to evacuate the store during the four-hour standoff.

Officers responded around 10:30 a.m. to the Westfield Wheaton Mall after 37-year-old Christopher Lawrence allegedly tried to steal a watch from the department store, the Montgomery County Police Department said. 

Lawrence barricaded himself inside a fitting room and reportedly threatened officers with the knife, according to police.

The department store was evacuated as emergency response teams and negotiators attempted to persuade Lawrence to leave the fitting room and turn himself over to police.
