from www.nydailynews.com – The brother of “Jersey Shore” star Mike (The Situation) Sorrentino is looking at more trouble now that a woman has hit him with more serious allegations of abduction.

Kathryn Redino, 24, of Manhattan, initially told cops that Marc Sorrentino [pictured center] punched her in the stomach – which he denied.

Now she’s charging he forced her to go on a limo ride to new Jersey and threatened to cut her with a broken champagne glass.

Redino told police she met Marc Sorrentino, who owns a porn company, and his more famous brother at a Manhattan nightclub Oct. 20.

They went to a friend’s apartment, and then piled back into the limo.

Redino claims Marc Sorrentino, 31, and his entourage drove her to New Jersey against her will, a police source said.

Once near his Howell, N.J., home, Marc Sorrentino allegedly told the frantic woman to get out “and go stand on the corner like the whore you are,” a police source said.

Redino said she countered with, “F— you, your mother’s the whore!”

She told police the remark prompted Marc Sorrentino, 31, to break a champagne glass and hold it against her neck, a police source said.

The next day, Redino filed a misdemeanor assault claim with the Howell police, claiming only that Sorrentino punched her, according to police records.

This week, Redino filed a complaint with the NYPD with the allegations about being taken to Jersey against her will and the threat. Howell cops are investigating that.

“While those allegations were not made to police, the young woman did make them when she was in court on the complaint, and so they are being investigated now,” a New Jersey police source said.

Marc Sorrentino also filed a complaint with Howell cops, accusing her of assault and lying about the incident.

Mike Sorrentino was in the limo but has not been charged with any crimes, police sources said.
