The family also said they wished to thank the public for their kind messages of support and the community of Ballymun who have "rallied around" to support them at this sad time.

They asked that the media respect their privacy and allow them to "grieve in peace".

The coach at St Kevin's Boys Football Club said today that Josh changed the team for the better when he joined two-and-a-half years ago. 

Gerard Reddy said Josh's team at St Kevin's are absolutely devastated at the loss of a lightening quick teammate and goal-scorer, who changed the team and lifted the dressing room when he came in two-and-a-half years ago. 

Speaking on RTÉ's News at One, Mr Reddy described Josh as a lovely, friendly teen who was always early for training, was not afraid of anything and had a very bright future.

He said Josh's mum "is absolutely devastated ... she couldn't comprehend the loss of him ... she can't deal with this.

"She always would have expected Josh to be famous, it's something she said to us ... but as she said, he is famous now for the wrong reasons.

"There definitely was a path for him somewhere, whether it was as a player in the League of Ireland or playing in England or Scotland, that was where he was going to end up because he had that much talent, that much pace, and the proper attitude.

"He came to us from Tolka Rovers with a very good attitude ... his game was so intense and he was an aggressive type player, but not aggressive off the pitch."

Mr Reddy said Josh's teammates "want to do something, as they won't be allowed to go to the funeral but [the team] will form a guard of honour.

"They are absolutely devastated and text messages are coming in all the time, they just don't know how to deal with it.

"We are all finding it very, very difficult, there's no answer to it," he said.

Gerry Reddy said in normal circumstances, Josh would have been training on a Tuesday night. 

He said this is a huge problem now - that Covid means "all these kids are out on the street" and there is nothing for them to do.
