Police have issued pictures of 15 people they are looking for in a tough new operation hunting those who breach bail or fail to show at court.
The PSNI said they are determined to close the net on suspected criminals through the Operation Relentless initiative.
More than 70 people have been arrested in the operation so far.
Bench warrants have been issued for the arrests of the people pictured here.
Officers are focusing on tracking down those people who have not turned up at court and are wanted for alleged criminal offences.
Area Commander Chief Inspector Jon Burrows said the three-week-old operation was already bringing results.
Mr Burrows said: “The operation has been running since the beginning of October and to date police have arrested 55 people on warrants and 18 people for breaching their bail conditions.
“Police will also be conducting nightly curfew checks on those persons charged with crime who have bail conditions and we will rigorously enforce bail conditions — if you are on curfew, expect us to call.
“Those charged with burgling homes will be prioritised.”
Mr Burrows said that police were determined to build on the drop in criminality witnessed over the past year.
He said: “Crime is at its lowest in Foyle in over a decade.
“This year there have been 100 fewer victims of burglary, over a 150 fewer victims of assault, and anti-social behaviour over the spring and summer was reduced by over 600 incidents.
“This means a better quality of life for all our citizens.
“This success could not have been achieved without the help and active support of our partners, community leaders and the public.
“Reducing crime and making people feel safer in their homes is of primary importance to police. The public should feel confident that officers in Foyle are taking all necessary steps to disrupt criminal activity in the local area.”
Welcoming the crackdown on people not turning up at court and breaching their bail conditions, DUP councillor Joe Miller said: “I hope this initiative brings such customs to an end and police are able to actually bring these people to book, instead of them disappearing in the mist.”
