GEORGE, Wash. -

The Grant County Sheriff's Office is asking for the public's help in locating four masked men who robbed a convenience store in George.

 Around 8 p.m. yesterday, four masked men entered Sandoval's Market, forcing two store clerks to hand over the store's cash. They then tied the employees up. 

Police say the men took off in a black 2002 Cheverolet Avalanche and abandoned it a short distance away on Beverly Burke Road Southwest. The Avalanche was stolen out of Tri-Cities. Police believe they abandoned the Avalanche and escaped in another vehicle. 

Anyone with information or anyone who may have seen anything is asked to call the Grant County Sheriff's Office at 509-762-1160. Tipsters can remain anonymous.
