Lincolnshire Police will hold a free bike marking session in Louth on Friday June 17.
The session, based at the Louth Cycle Centre in Newbridge Hill, will run from 10am until 1pm.
Bicycles will be UV-marked and safety checked for free (any required new parts are not included).
All cycles marked on the day will also be entered into a free prize draw to win a £20 gift voucher at the Louth Cycle Centre.
The scheme is in support of National Bike Week - find out more at www.bikeweek.org.uk.
