A crew working to repair a broken water main was robbed at gunpoint early Sunday morning in Temple Hills, Maryland, according to the Washington Suburban Sanitary Commission.

Four WSSC employees were working in the 4100 block of 24th Avenue about 2:45 a.m. when a suspect with a gun approached them and took some of their personal belongings, Prince George's County police said. The suspect then ran away toward Kenton Place.

WSSC said the employees were shaken but unharmed.

A spokeswoman for WSSC, Lyn Riggins, told News4 the company is taking extra precautions for its crews since the robbery.
