A group of teenagers have been praised for helping a man who had collapsed in a town park.

Nicholas Smith, 33, from Beaconsfield Road in Lowestoft, was walking with his two children and his friend's dog on Wednesday, May 31.

As they were passing Fen Park at around 4.45pm, they saw a man lying on the ground next to a bench.

A group of teenagers was standing nearby and Mr Smith asked them if they had seen what had happened to the man but they hadn't.

"Immediately, they gathered up and came over to see how he was," Mr Smith said.

"They were really good with him. They were talking to him, keeping him conscious."

They helped up the man, who said he suffered from vertigo and had fallen on the ground, and put him on the bench.

Mr Smith, who works as a team leader at a food warehouse, then went home to drop off his children and the dog before returning to the park.

He met some of the teens again and they told him that the man had said he wanted to go home and three of the group were accompanying him there.

After crossing Tom Crisp Road, though, the man had collapsed again.

Mr Smith said that one of the teens had rested the man's head on their lap, another was calling the ambulance and the other had taken his name, age and details of his medications.

"They were really in control of the situation," he said.

A passerby on a bike - who Mr Smith only knows as Josh - arrived and went to get a defibrillator.

By the time he returned, the ambulance had arrived.

Mr Smith said the teens "definitely need some recognition of some form because I believe there is a lot of negativity about youth around the area".
