A city-wide chasing game is taking place in Dublin this evening.

Runners are asked to stop at a number of checkpoints before they finish the course through the city centre.

If caught by a 'chaser', participants become chasers themselves. Runners are only allowed to travel by foot or public transport.

The event kicks off at 5pm on Aungier Street.

People can sign up on the Alt Events Facebook page to take part.

Co-director of Alt Events, Danny O'Leary, says it is not just about how fast you can run:

The event will finish in Smithfield Square, where an evening of Halloween activities is taking place.

Among the events will be a big screen FIFA tournament; a stage featuring magicians, sword swallowers, dancers, and DJs; and a zip line.

You can find out more information about the Smithfield event, hosted by Happenings, on their Facebook page.
