A staff member and two patients, one of whom was pregnant, were hurt in the crash on Wednesday.

“We are pleased that only minor injuries occurred,” Planned Parenthood said in a statement. The organization said there was “extensive damage to the waiting room” and the clinic would be closed for several weeks.

The stolen truck belonged to a Newark bakery, the authorities said.

Mr. Alcius pleaded not guilty in a court appearance on Friday. He is being held at the Essex County Correctional Facility in Newark, and his next court appearance is scheduled for Feb. 21.

This month, New Jersey state lawmakers voted to restore millions of dollars in funding for health and family planning clinics. The funding had been cut under the administration of Gov. Chris Christie, a Republican.

The new governor, Philip D. Murphy, a Democrat, was endorsed by Planned Parenthood.
