Foyle Search and Rescue responded to almost 200 incidents on the River Foyle last year it has emerged.
Figures released by the charitable organisation reveal that they attended 191 incidents during last year.
A spokesperson for the organisation said: “Volunteers rescued 18 people from the river. Sadly we returned the bodies of four people to their families. There were also 74 instances where distressed people were taken away from the river’s edge or bridges. We also approached 94 people we thought may have needed our help. In addition, volunteers also carried out one animal rescue.
“This would not have been possible without the continued generosity of both the local community and statutory agencies, for which we are extremely grateful.”
The organisation which founded in 1993 in response to the number of lives lost to the River Foyle also confirmed that their volunteers gave over 10,000 hours of unpaid service to the local community in the last 12 months.
