Police investigating a bomb attack in Derry last night came under attack from petrol-bombers.
The security operation in the Creggan area of Derry, following an attack on police in the area on Sunday is continuing.
A number of homes in the Circular Road and Creggan Heights area remain evacuated.
Police came under attack from a large number of youths throwing bottles and stones during the operation last night.
A number of petrol bombs were also thrown at police.
No-one was injured during the disorder.
Three boys aged 13, 14 and 16 were arrested on suspicion of a number of public order offences.
All three remain in custody assisting police with their enquiries.
Area Commander Chief Inspector Tony Callaghan said: “We would appeal to people with influence in the community to do what they can to dissuade young people from getting involved in this type of behaviour.
“We realise the disruption this operation has caused to the local community, many of whom have been out of their homes for some time. We appreciate their understanding, patience and co-operation. We know people understand that our priority must be their safety and the safety of our officers.
“We also have to carry out a scene examination - this is vital but often a painstakingly slow process - and one which will continue. It is imperative that we make every effort to secure any evidence from the scene that could potentially lead to people being charged and brought to justice. We know the public want us to investigate this in a thorough and professional manner.
“Police would again like to thank the community for their patience while we work to identify the persons who have caused this disruption in their community. We are determined to put these people before the courts.”
