Eerie footage of a suspected bomber wheeling a bicycle along the River Foyle before walking casually away has been released by the PSNI in a bid to catch the person responsible for the double bomb attack.
Two bombs were left, one in a rucksack and another attached to a bicycle, near Derry City Council building in September last year.
The rucksack was discovered by a Foyle Search and Rescue volunteer before 11pm on Thursday September 20, 2012.
Shortly after that discovery, police who had been called to the scene discovered a secondary device attached to a bicycle chained to a railing just a short distance away.
Neither device exploded and police have now issued CCTV images of the supect in a bid to identify him.
Chief Inspector Jon Burrows said: “Either device had the potential to kill or injure anyone in the vicinity, had they exploded. The second device on the bike was timed to go off when the security forces were in the area dealing with the first device in the rucksack.
“The bike bomb was on a walkway that is frequently used by walkers and joggers and people on their way home from a night out. We were lucky that no one was killed or seriously injured.
“I would appeal to anyone who recognises this individual to contact police on 0845 600 8000 ext 64911. Alternatively, anyone who does not want to provide their details can phone the independent charity Crimestoppers on 0800 555 111.”
Police are also making an appeal in relation to the rucksack and bicycle. They want to hear from anyone who recognises the rucksack or the bicycle. The rucksack is a black Compass model with a blue and red design. The bike is a blue framed Freerider model.
