Two people were injured on a Harrison Hills picket line when they were struck by security vans in separate incidents.

Linda Rusen, spokeswoman for the Harrison Hills Teachers' Association, said a van owned by Michigan-based Huffmaster security struck a teacher at Hopedale Elementary.

Jennifer Starr, a teacher who was picketing at Hopedale Elementary, said she witnessed the accident.

"We were having a peaceful demonstration," said Starr. "We were walking with our picket signs and this white Huffmaster van just came straight through and she had her back turned, and he hit her. He just hit her."

Starr said the teacher was limping at the accident scene.

The teacher was transported by ambulance to Trinity Medical Center, where she underwent treatment. Police said the teacher was not seriously injured.

In a separate incident, the unions said another union member was injured on the picket line when she was clipped by a Huffmaster van's mirror.

Huffmaster was hired by the Harrison Hills school board to provide safety during the strike.

"As picketing teachers are on the picket line, we are very concerned with our safety. We are also very concerned about the safety of the children who are being sent to school," Rusen said.

In a news release, Superintendent Jim Drexler said there were "attempts by pickets to block security vans bearing substitute teachers."

Police Chief Ron Bone said no one had been cited and both incidents remained under investigation Monday afternoon.

Drexler said he is waiting to see the police reports before he gives any further comment on the matter.

Drexler alsotold NEWS9 there was a 36 percent district-wide attendance rate on Monday. Drexler said he hopes attendance will grow and said the district has employed more than 60 substitute teachers.
