Police believe a recent attack of a Hoboken couple may be connected to a violent game known to teens as ?Knock Out.?

Five teens were arrested in connection with the attack, which occurred on the corner of 9th and Madison. Police say the teens went after a woman?s purse and then pounced on the male victim when he tried to defend the woman.

Two of the teens were arrested at Hoboken High School. A third teen, 18-year-old Malik High, attends an alternative school in Hoboken. Police believe High was the instigator of the group. High is charged with robbery and using juveniles to commit a criminal offense. Hoboken police say as many as three arrests are on the way.
