Warning follows boat burglaries in Surrey
Boat owners and walkers have been urged to be vigilant following a spate of break-ins at vessels moored in a canal in Surrey.
Surrey Police said thieves had targeted craft on the waterway off Bridge Road, Chertsey at least four times.
Electrical items including a television and MP3 player were stolen from a riverboat during the latest incident on Monday.
The force has appealed for anyone with information to contact officers.
Sgt Andy Gibbon said: "There are regular walkers and boat owners who may have seen something that could help officers track the offenders and bring them to justice.
"It would appear there have been a number of similar offences and I would urge anyone who has suffered a break in to contact police.
"There is a close knit community around the river and I would advise that everyone look out for each other in order to put a stop to this type of distressing offence."
