Murdered slumlord’s son robbed at knifepoint

The pre-teen son of slain slumlord Menachem Stark was robbed at knifepoint Monday evening in Brooklyn, police sources said.

Abraham Stark, 11, was near Lorimer and Union streets in Williamsburg at 7 p.m. when three teens approached him and demanded his bike, sources said.

One of the punks whipped out a knife as another shouted, “Kill him!” according to sources.

Witnesses started screaming, sending the trio of teen thugs fleeing with the bike, sources said.

Stark was unharmed in the robbery and the bike was found on a nearby street a short time later, police sources said.

The robbers are still on the loose, sources added.
