Lincolnshire Police are sending a stern warning to youngsters after a number of criminal damage incidents were reported in a derelict factory in Wragby, near Lincoln.
The incidents keep happening at the Beehive Works on Louth Road, were there is evidence of forced entry and areas where small fires are lit.
PC Duncan Bustin, from Horncastle Police Station, said: “It appears that local young people are using the Beehive Works as an area to play or hang out in.
“Entering this building without permission is burglary and anyone found on the premises may be arrested and dealt with robustly.
“I am urging parents to speak to their children and ensure they understand that, for their own safety, they must not trespass onto these premises.”
