Nassau County police said two men were arrested after they robbed and attempted to strangle a 21-year-old man they were helping move out of his home Monday in Seaford. Both suspects, police said, were acquaintances of the victim.

One of the suspects, police said, had set the plan in motion by calling the victim and offering to help him with his move.

The suspects, Christian Dowd, 20, of Roosevelt Boulevard, Massapequa, and Patrick White, 39, of Godfrey Avenue, Bayville, were arrested in Glen Cove less than 3 1⁄2 hours after the crime was committed — after the victim told investigators one of the men had a girlfriend who lived there, police said.

The suspects were arrested at that house by Seventh Squad detectives and Glen Cove police at 6:50 p.m.

Both were charged with first-degree burglary, first-degree robbery, second-degree strangulation and second-degree assault. They face arraignment Tuesday in First District Court in Hempstead.

Police said Dowd and White were acquaintances of the victim and arrived at the victim’s home on Somerset Drive at 3:32 p.m. after one of them called and offered to help the victim move. While the victim was loading sneakers into plastic containers, police said, Dowd and White began to beat him, then attempted to choke him with an extension cord before tying his hands and feet. The two suspects then stole cash, an iPhone and sneakers valued at about $1,500, police said.

The pair then fled.

But the victim managed to escape the house and alert neighbors, who called police.

The victim was later treated at a hospital.
