A 51-year-old Alaska woman was critically injured yesterday in a moped crash on Diamond Head Road.

The accident happened about 3:08 p.m. near Makalei Place.

Police said the woman sustained "open head wounds" when she apparently fell off her moped.

The woman was not wearing a helmet.

Two others traveling on mopeds with her were not involved in the crash.

Speed and alcohol were not factors, police said.
