Police have released four men who had been arrested after an attempted car hijacking and the discovery of an explosive in Londonderry.

A gang of masked men tried to take a delivery driver's vehicle at Hollymount Park on Friday night.

The explosive was later found close to a sports pitch on Corrody Road, in Gobnascale, where children were playing football.

The men, aged 54, 32, 34 and 29 , were released on Monday, police said.

Speaking on Sunday Ch Supt Nigel Goddard said the explosive device had been "recklessly left in a public area".

"[It was] just metres away from houses and a sports area where a number of children were playing football," said the police commander for Derry City and Strabane.

Army bomb experts took the explosive away for a forensic examination.

Democratic Unionist Party (DUP) MP Gregory Campbell told ³ÉÈË¿ìÊÖ Radio Foyle it was "absolutely deplorable" that young lives have been put at risk.

"We all have to be grateful to the police who acted quickly," he said.

Hopefully people will assist them to ensure those responsible will be brought before the courts".

Social Democratic and Labour Party (SDLP) assembly member Sinead McLaughlin said it was "reprehensible" that the explosive had been left in the area.

"For armed men to try and hijack [a car] and then leave a viable device where kids are playing the next morning is beyond reckless," she said.

Sinn Féin councillor Christopher Jackson said the area was popular with residents, particularly dog walkers.

"There is a lot of anger from residents, who would use this area to go and clear their head," he told ³ÉÈË¿ìÊÖ Newsline.

"There is also a lot of anger from from parents of young children who were playing a Gaelic competition here."

A 16-year-old boy arrested on suspicion of attempted hijacking in a separate incident in Derry has also been released on bail.

He had been questioned after the incident on Lower Bennett Street on Saturday night.
