THE family of a care worker beaten to within an inch of his life as he reportedly tried to protect his son from bullies has said their "life sentences began that day".

Alan Willson was left “fighting for his life” at the Royal Sussex County Hospital in Brighton following the shocking incident at Longcroft Park, Worthing, shortly before 7.30pm on Easter Sunday.

Five teenagers, all under 18, were arrested on suspicion of attempted murder before being released on bail with "strict conditions".

Sussex Police confirmed to The Argus yesterday that the youths remain on conditional bail while investigations continue.

Alan's wife, Annie, has shared a message on Facebook to update the community.

She said: "I would like to say how grateful we are that the community came together to support my family and thank you to everyone who donated.

"The money raised has been spent on adapting our home for Alan and buying stuff he needs on a daily basis.

"My son is coping very well and is trying to be brave for us.

"On that day our life sentences began. Things like popping to the shop, having a bath, and taking five minutes out have to be carefully planned.

"Thank you again, everyone, for your support."

The 46-year-old rushed to the park from his house after learning teens had thrown his son to the ground and hurt him.

But when he arrived and tried to stop the abuse the youths turned on him, allegedly beating him and leaving him with severe injuries.

Wife Annie shared a distressing image showing the extent of his wounds on social media.

She claimed her husband's assailants "kept hitting him with a log" and he was left needing surgery for multiple bleeds on his brain.

Two days after the brutal attack, police confirmed they had arrested four boys on suspicion of attempted murder and grievous bodily harm with intent.

The force announced then that a fifth boy had been arrested, again on suspicion of attempted murder.

Yesterday, Sussex Police said the suspects remain on conditional bail while investigations continue and that the victim has returned home from hospital.

Previously, Detective Inspector Simon Dunn, who is leading the investigation, said: “The assault and the build-up to it occurred in a public park in daylight, so it was likely that other people would have witnessed the assault or the suspects running from the scene.

“I am keen to hear from anyone who has information but is yet to come forward.”

Witnesses can call 101 quoting Operation Swallowtail.
