The Portland Police Department will give away bike helmets for children on Wednesday.

The department will also offer bike registrations, hold a bike rodeo, provide bike safety lessons and other children’s activities – including a dunk tank, with proceeds going to the Police Activities League.

A limited number of helmets is available.

The event will be held from 3 p.m. to 6 p.m. Wednesday in the Preble Street Extension parking lot across from the Hannaford grocery store.

For more information, call 780-0495 or 756-8135.
