Police released surveillance video of the men they say violently robbed a jeweler in Downtown Brooklyn, fleeing with $800,000 worth of jewels.
Police say three of the four suspects were dressed as construction workers when they entered the store at 60 Court St. just after 5 p.m. Thursday.
One of the suspects pulled a gun on the 67-year-old owner and violently beat him up, before running off with the jewelry.
The store owner was taken to the hospital to be treated for head wounds and is expected to be OK.
Police say the surveillance shows the men jumping turnstiles at the Borough Hall subway station after fleeing.
