A former Rikers Island inmate and Bloods gangbanger who was awaiting a $450,000 settlement from the city was fatally shot at a Brownsville public-housing complex, authorities said.

Robert Hinton — who made headlines in 2012 when it was revealed he had been “hogtied” with shackles and savagely beaten by correction officers — was gunned down outside a building in the Van Dyke Houses just after 11:30 p.m. Thursday, police said.

The 28-year-old Hinton had won his settlement just two months ago. He died at Brookdale Hospital, authorities said.

Investigators still do not have a motive or suspects in the slaying.

“Our hearts are heavy with the news today of our client Robert Hinton’s death,” said Leo Glickman, whose firm represented Hinton in the lawsuit.
