Police are appealing for information after a substantial quantity of lead was stolen from the roof of a school in Derry.
The theft at Long Tower Primary School on Bishop Street occurred sometime after 6 o'clock on Monday night and 8 o'clock yesterday morning.
Police in the city are urging people to look out for unusual or suspicious activity at all schools, saying 'Work men' working at unusual times or out of the ordinary 'comings and goings' can all be signs of illegal activity.
Neighbourhood Inspector Trevor McKeown said: "These type of thefts cause damage which need to be repaired and is costly for the schools.
He said police are appealing to anyone who lives near schools to report any activity around the buildings, outside of school hours to us straight away.
