Detectives are hunting two teenagers who set upon a cyclist and stabbed him in the skull with a piece of bike frame

Victim Chris Shields, 39, suffered a depressed fracture in the attack and had to undergo surgery.

The incident has left him traumatised and living in fear, and sparked shock and outrage among residents.

His mother Barbara Chamberlain has described the youths responsible as attacking 鈥渓ike a pack鈥?of animals 鈥済oing in for the kill鈥?

They were male and estimated to be about 14-15 years old, she said, adding that there were about 10 involved.

Mr Shields, of Hallwood Park, Runcorn , was released from hospital on Monday and will have to return for follow-up appointments.

Mrs Chamberlain, 60, said the attack happened after the gang started 鈥榞iving him verbals鈥?as her son visited Halton Lodge shops on his bike.

There was a verbal exchange and Mr Shields threw his bike towards the boys, she said, then said that was enough and tried to leave.

However, he stumbled into bushes on Whitchurch Way and was punched and one of the attackers stabbed into his skull with a piece of frame that connected to the seat of his bike.

His mother said a girl managed to move him to safety and called 999 and also his brother, as he pointed the numbers to her, unable to speak or walk himself, leading to the brother arriving before the emergency services.

She believes a rapid response medic and ambulance arrived and took him to Fazakerley hospital.

Cheshire police said officers were called to Whitchurch Way in Halton Lodge at 8.27pm on Thursday, April 6.

A spokesman said two of the teenagers had become violent and assaulted the victim, hitting him in the head with a bicycle seat.

He said the first suspect was described as white boy, aged 14 to 16 years old, about 5ft 6ins tall, with short dark hair.

He was wearing a black waist length puffer jacket.

The second suspect was slim, in his teens, with thin blonde shoulder-length hair and a slim face.

He was wearing a grey hooded top.

There had been up to 12 teenagers present at the time. Detectives are investigating and a dispersal zone was in place over the weekend.

Mrs Chamberlain said: 鈥淎 gang of youths started giving him a load of verbals one way or another. He gave a little bit back like 鈥榞o away鈥?as you do, trying to get past them.

鈥淭hey started coming at him. He was obviously intimidated.

鈥淗e said 鈥榗ome any further I might throw my bike at you in defence鈥?which he did in the end.

鈥淭en of them were about to jump him. He threw the bike, went to pick it up and said 鈥榞o away鈥?

鈥淗e could see out of the corner of his eyes a lad on his bike removing the saddle from it.

鈥淗e ran away from it, tripped over into some bushes at which point they all followed him, jumped in, punched him in the head and he got stabbed in the head with the post that goes in the bike for the seat.?/p>

Mr Shields said he enjoys riding his bike and it helped him deal with depression. He said he now feels 鈥渁nxious and panicked.?/p>

He said: 鈥淚 can鈥檛 think straight.

鈥淚 can鈥檛 get the words to describe the way I鈥檓 feeling ?anxious and panicked.

鈥淚鈥檝e come out of hospital and there are millions of things going through my head and it鈥檚 making me cry and upset.

鈥淚 don鈥檛 know whether I鈥檓 coming or going.

鈥淚 get very upset, angry and I鈥檓 very worried about myself.?/p>

Detective Inspector Clare Coleman, of Runcorn CID, said: 鈥淭his was a particularly vicious attack which has left the victim with serious injuries.

鈥淭he victim has since been discharged from hospital, but understandably he is very shaken by what has happened.

鈥淲e are determined to do all that we can to trace the people responsible for this appalling act.?/p>

She added: 鈥淲e believe that between 10 and 12 teenagers were present at the time this incident took place and I would urge parents in the local area speak to their children about what happened in case they have any information that could assist with our enquiries.

鈥淚鈥檇 also like to appeal directly to the teenagers who were involved to come forward and speak to us about what happened, if you do not want to speak to officers directly you can also contact Crimestoppers anonymously on 0800 555 111.?/p>
