A cyclist was filmed tackling an opportunistic thief who had jumped on his bike as he turned his back.

He had left the bike alone and unlocked for just 17 seconds, when someone tried to jump on it and cycle away in Dublin.

However, he evidently picked the wrong bike to steal, as its owner quickly returned and leapt on him to stop him from getting away.

The fleet-footed owner works for Dublin cycle store 360 Cycles which posted the video on social media.

‘One of our senior mechanics was very lucky to get away with about €200 worth of damage rather than losing his carbon racing bike.

‘This happened in Clontarf over the weekend and we would like to urge all bike owners to lock their bikes at all times even if you are just leaving it for under a minute.’

One commenter, Luke Nolan, said: ‘You’d have to bolt it down in this city. Great reaction from the owner. Hope the bike was unharmed.’
