A Northolt teen who hit the headlines after punching a girl during a waterfight organised through Facebook has been jailed for a string of crimes.

Daniel McInerney, 17, of Dolphin Road, Northolt, was famously unrepentant after he punched the 15-year-old who threw pink water over him during the mass waterfight in Hyde Park at the end of July.

However, today at Isleworth Crown Court he admitted having a bladed article in May, two charges of robbery, one of attempted robbery and one of theft – all in a few days in July.

He was first arrested in May after he and another teen ran away from two police officers they spotted walking down Ellesmere Road, Greenford.

Prosecutor Azura Khan told the court: “The boys ran off. The officers followed them and this defendant was seen to remove his hooded top and throw it away and then discard something silver over a garden wall.

“Other officers with a dog retrieved both the top and a knife.The defendant was questioned and given police bail.”

Eight weeks later on July 15, McInerney and two others boarded a 105 bus from Southall to Greenford and attacked a top-deck passenger with a stick in an attempt to rob him of his mobile phone.

Ms Khan said: “The first youth struck the man with a stick and then this defendant got hold of the stick and struck him with it while the third kept watch..

“The victim had two cuts to his head which required a total of nine stitches. He also had facial bruising and was kept in hospital overnight for observation.”

Three weeks later the victim was on another bus when he spotted two of his attackers, followed them and called the police. McInerney was arrested again but refused to answer police questions. “CCTV video from the bus showed him clearly wielding the stick,” said Ms Khan.

The day after that attempted robbery, McInerney and others launched an attack on a group of people sitting in a car near Northala Fields.

Counsel told the court: “The people were asked what they were doing there and then set upon by the group who took their mobile phones, money and other items, leaving them with bruises and abrasions.”

A few days later McInerney and others were in Bunny Park, Hanwell, where they threatened two 15 year-old schoolboys before snatching their bikes, later dumping them in a river.

McInerney was again arrested and made full admissions, but refused to name the others who took part.

Later on the same day in Ealing Broadway he snatched a mobile phone from a man crossing the road. But it was seen by two plain-clothes officers who chased and caught him.

His counsel, Heather Hope said he had been remanded in custody since August and found it “very difficult”.

He had not been in trouble before and had committed these offences just before hearing that he had been accepted for basic training by the Army.

She said: “This was a few days of complete madness for something that was quite pointless.

“He recognises the fear and intimidating that he must have put his victims through and there is no suggestion that he is going to go out and do something like this again.”

But Judge Sam Katkhuda said he had to consider the victims and there was no alternative to custody.

Sending him to a young offenders' institution for 12 months, the judge told him "Altogether there are five offences – two of which [robbery] carry a life sentence.

“I have to consider the question of whether you are a dangerous person. But I am going to be very lenient. Don't come back to court again.”
