Police are appealing for witnesses after a number of razor blades were placed on a cycle path in Belfast.
A cyclist discovered the blades after his tyre was damaged while cycling on the Cregagh Road on Saturday.
The incident was reported to police around 3.45pm.
Sergeant Tom Donnelly said that it was an "incredibly dangerous thing to do".
"Whoever was responsible could have caused serious injury or worse to anyone using the path had this not been found by a member of the public, who themselves were extremely lucky to avoid being badly hurt," he said.
“I would like to commend this member of the public for their vigilance in reporting this matter to police.
"I would appeal to anyone who saw any suspicious activity in the area at any time, or who can provide any information as to whoever carried out this reckless act, to contact police on 101 quoting reference CCS 1160 of 20/07/19.
"Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111 which is 100% anonymous and gives people the power to speak up and stop crime."
