Jim Hennessy, a spokesperson for the police force, said officers received a 9-1-1 call shortly after 6 p.m. Rescuers were able to make their way to Patridge Island, a national historic site of Canada located in St. John Harbour.
Hennessy said they quickly found the four youths, one of whom had a severe cut on his hand.
All four of the boys were taken to shore and transported to Saint John Regional Hospital to be checked for any other injuries. Hennessy said the youths were able to go home later than night.
It’s believed the kids got to the island by walking along the breakwater – a strip of land connecting Saint John and Patridge Island.
Police are reminding citizens that it is illegal to be on Patridge Island without consent from the Department of Fisheries and Oceans and or the Canadian Coast Guard.
Hennessy said no charges will be laid in this instance.
