A woman was injured Thursday morning when she jumped from a moving bus in Anaheim and hit her head on the ground, police said.

Around 6:50 a.m., a woman on an Orange County Transportation Authority bus going westbound 20 to 25 mph on East La Palma near North Tustin Avenue when she opened an emergency window and jumped out, said Sgt. Daron Wyatt of the Anaheim Police Department.

Two men nearby rushed to her aid, and she became abusive and assaulted them, Wyatt said.

An Anaheim police officer on his way to work saw the commotion and held the woman, whose name was not released, on the ground until other units arrived.

She was detained in handcuffs and sat on a curb when she went into cardiac arrest.

“She was conscious and talking and then she just keels over,” Wyatt said.

Anaheim Fire & Rescue paramedics revived her and took her to a hospital.

Her condition was not immediately available.

The bus stayed at the scene for several hours and two traffic lanes were briefly closed.

Passengers had to wait for another bus, Wyatt said.
