from www.nydailynews.com – A Brooklyn groping suspect – nabbed skulking down a street with his pants unzipped and porn playing on his phone – could be linked to six subway attacks, police said Tuesday.

Joshua Flecha, 32, of Queens, was identified by one victim after his arrest, and cops were putting him in more lineups.

Flecha, who has two drunken-driving busts on his record, was caught by anti-crime officers on the lookout for the perverts responsible for a string of 20 sex attacks in several neighborhoods.

They noticed him walking on Greenwood Ave. in Windsor Terrace at about 2:30 a.m. – and again 45 minutes later on 17th St. and 10th Ave.

The cops thought he might be trying to breaking into parked cars and grabbed him. They said his pants’ fly was open and there was an X-rated video rolling on his cellphone.

They noticed that Flecha, who was also carrying pot, resembled a police sketch of a suspect who has groped a half-dozen women in the Seventh Ave. F train station.

A 37-year-old woman who reported a groper grabbed her breasts and exposed himself on May 7 picked Flecha out of a lineup, police sources said.

Flecha lived in an apartment in Astoria with a roommate until a couple of weeks ago.

“He seemed like a nice guy. He never gave me any problems as a tenant. No one ever complained about him,” said the building super, Tom Yzeiraj.

The subway pervert is believed to be responsible for six attacks since March, but other men are thought to be behind more than dozen molestations above ground.

A week ago, police arrested Adolofo Martinez, 26, and charged him with grabbing the rear end of a young woman in Sunset Park the night before.

Two other predators still at large may be behind the rest of the attacks in Park Slope, Sunset Park, Greenwood Heights, Windsor Terrace and Bay Ridge.
