In Derry, Northern Ireland, a bomb was discovered close to where kids were playing football.
Just a few metres away from the location of the “viable” explosive are more than 20 people.
Following a failed hijack attempt in the city on Friday, police conducted a large-scale security operation and found the device.
Four men, aged 54, 29, 34 and 32 have since been arrested, and they remain in custody pending further enquiries.
Derry City and Strabane area commander, chief superintendent Nigel Goddard said the bomb has been taken away for further examination.
‘A number of cordons remain in place as police continue to search the area as part of our investigation,’ he added.
‘We would like to thank the local community for their patience and understanding during this time.
‘This explosive device was recklessly left in a public area, just metres away from houses and a sports area where a number of children were playing football.
‘Four people have been arrested and a number of searches have been carried out by detectives investigating this incident and an attempted hijacking on Friday.
‘They remain in custody assisting us with our inquiries.’
Mr Goddard added: ‘Our focus remains firmly on keeping people safe against the threat posed by violent groups.
‘No matter what level of involvement people have with any criminal or terrorist activity, we will investigate and where appropriate, put people before the courts to answer for their actions.
‘Our investigation into this incident is ongoing, and we strongly urge anyone with information, suspicions or concerns about dangerous and illegal activity in our community to contact us on 101.’
