Investigators suspect a rash of street attacks Sunday night in Freeport are related, Nassau County police said Tuesday.
The robbery and attempted robberies, including an attack that left a 34-year-old man stabbed four times, happened in a one-hour span from 10:50 to 11:50 p.m.
"Based on the location, time frame and commonality of the victims, we believe that they were related," said First Squad Det. Lt. Robert Galgano, who declined to describe the similarities but said language barriers may have kept the robbers from taking cash in two of the attempted robberies.
Police said the first attack, a robbery, occurred near Davis and Dutchess streets, the second about 25 minutes later in an alleyway adjacent to 64 Commercial Ave. and the third near Southside and Sportsmans avenues at 11:50 p.m.
The victim in that last attempted robbery was attacked by two men, police said, one with a gun and one a knife.
Galgano said one of suspects displayed a gun. The man was stabbed four times when he tried to wrestle the gun from an attacker, suffering a lacerated liver and a partially collapsed lung, Galgano said.
Police said he was taken to a hospital by ambulance and was in stable condition.
The first incident involved three attackers, police said, who were on bicycles.
They confronted the victim, a 51-year-old man, punched him in the face and chased him to a nearby residence -- where he activated a motion detector that police said set off floodlights and scared the robbers. The trio fled on foot with the victim's cash, police said, leaving the bikes.
The second attack occurred when a 62-year-old man was struck from behind in an alley by two men. They ran away through a parking lot.
The victim was taken to a hospital with cuts to his head and face. No money was taken.
Nassau police are also looking for two suspects they said attacked a 53-year-old man in Roosevelt -- which is not thought to be related to the ones in Freeport. He was beaten and robbed while walking on Harts Avenue on Sunday night.
Police said anyone with information can call Crime Stoppers at 800-244-8477.
