An Army bomb disposal team has made safe a suspect device found in a north Dublin park this morning.
The device was found in Fairview Park shortly after 10am and the Army ordnance team detonated a controlled explosion to make the device safe. A technical team later examined the remnants of the device and gardai are investigating whether it was viable or an elaborate hoax.
Earlier today, gardaí refused to link the device with today's visit by a British monarch to Croke Park where the Princess Royal was due to attend the Ireland v Scotland rugby international.
The device, which gardai have described as viable was found close to a location where two pipe bombs were found by a man walking his dog last November.
Diversions have been lifted and delays have eased significantly on the Clontarf Road, Malahide Road, Howth Road and the North Strand.
The park is close to Croke Park where Ireland hosts Scotland in today's Six Nations Rugby Rugby International.
However, it is not clear if the incident is related to the visit today by the British royal.
Security cordons were in place on streets around Croke Park from early morning and several streets closed for a period either side of the match.
Match goers were subjected to security checks around the ground and only people needing access to businesses, local residents and others with passes were allowed through.
The Princess Royal watched Ireland beat Scotland from the VIP enclosure in the Hogan Stand. The stand was named after gaelic footballer Michael Hogan, who was among the 14 murdered by British troops on Bloody Sunday in 1920.
