ST. JOHN'S, N.L. -- Recreation facilities are back open in St. John's today as police investigate a homemade explosive device found Monday on a city-run tennis court.

Insp. Brian Dowden of the Royal Newfoundland Constabulary says the explosive is not on par with the sort of roadside bombs planted in Afghanistan, but nor is he dismissing it as a prank.

He says no member of the public or police was in danger as a robot was used to remove the device at Wedgewood Park and take it apart.

As a criminal investigation continues, police would not describe the device in detail nor confirm whether it had a detonation mechanism.

Dowden says police are not aware of any surveillance footage that might help identify anyone responsible.

Police are reminding the public not to touch suspicious packages and to immediately notify police.

St. John's temporarily closed all outdoor recreation facilities in the city after a worker found the device
