CLARKSTOWN - A Pearl River teacher was arrested on cocaine charges after a man she was with was stabbed on Saturday, police said.

Clarkstown police said Denise Christensen, a special education teacher at Pearl River High School, had cocaine in the car she drove to Nyack Hospital, where she took a man who had been stabbed twice in the torso.

Christensen, a 53-year-old Pearl River resident, has been placed on administrative leave, the Pearl River school district said.

The man who was stabbed, Carl Mason, was also arrested on drug charges, police said.

Officers responded to Nyack Hospital around 1:20 p.m. Saturday when Mason walked into the emergency room with the stab wounds, which were not life-threatening, police said.

Christensen had driven Mason, a 29-year-old Sparkill resident, to the hospital, and both of them were uncooperative about how the stabbing occurred, police said.

Police said they found cocaine in Christensen's car, and she and Mason were both arrested.

Christensen was charged with fourth- and fifth-degree criminal possession of a controlled substance, felonies, and seventh-degree criminal possession of a controlled substance, a misdemeanor. Mason was charged with third-degree criminal possession of a controlled substance, a felony, and seventh-degree criminal possession of a controlled substance.

Christensen was arraigned in Clarkstown Town Court and taken to Rockland County jail on $2,000 bail. She is due back in court on Wednesday.

Mason was being held at the hospital in protective custody.
