In what police believe was a targeted attack, a Valley Stream man who left his house early Monday was brought back inside by two armed intruders who bound him and another person with duct tape and ransacked the home.

Authorities say the victim, 34, may have known the men, and they asked him about a gold chain he owned.

A second victim, a 36-year-old woman, already was inside the house when the burglary took place. She, too, was bound with tape and was sexually assaulted by one of the intruders, police said.

“Detectives believe that this robbery and sexual assault is an isolated incident and not a random act within their community,” said Det. Lt. Richard LeBrun at a news conference Monday night at police headquarters.

The crime unfolded around 7:10 a.m. at the victim’s East Hawthorne Avenue residence.

Authorities say the first assailant was armed with a handgun. The second had a rifle in a duffel bag. They stole jewelry and an undisclosed amount of cash, and fled. Police said the men were driving a brown, older model SUV.

The male victim was eventually able to free himself and call 911.

The first suspect was described as 6 feet tall with a slim build. He was wearing a black hooded sweatshirt, black jeans and black boots, police said.

The second man was 5-feet-7 with a medium build. He was dressed similarly to the first man, but wore a dark face mask that covered his mouth.
