Arsenal and England midfielder Jack Wilshere was arrested in the early hours of the morning following a "fracas", according to a spokesman for the player.

Wilshere, who came on as an 84th-minute substitute in yesterday's 2-1 win over Blackburn, was arrested but released on bail.

The statement, issued by the Wasserman Media Group on behalf of the 18-year-old, went on to assert Wilshere was "unlikely" to face charges.

The statement read: "Jack Wilshere was arrested by police in the early hours following a fracas but was released on bail later. The police have made it very clear that he is an important witness to the incident and played the role of peacemaker and is unlikely to face any charges as a result. Jack has made it very clear he will co-operate fully with the police investigation.''

Wilshere made his England debut in the friendly against Hungary earlier this month but was named in the Under-21 squad for the upcoming matches against Portugal on September 3 and Lithuania four days later.

With the senior side also facing Euro 2012 qualifiers against Bulgaria and Switzerland many had tipped him to retain his place in the full squad instead.

A Met Police spokesman said: "Police were called at approximately 2.45am on Sunday 29 August following reports of an assault on Kensington High Street.

"Officers and London Ambulance Service attended and discovered a man and a woman suffering injuries. The woman had suffered a broken and dislocated elbow; the man was treated for a minor facial injury. Both went to a west London hospital for treatment.

"Officers subsequently stopped a vehicle and arrested four men on suspicion of assault. They were taken to west London police station and subsequently bailed to return in mid-October, pending further inquiries."

It is believed that Wilshere was out socialising after appearing in Arsenal's Premier League victory against Blackburn.

Earlier this week Arsenal boss Arsene Wenger said he was surprised that the youngster had been omitted from Fabio Capello's England squad to face Bulgaria and Switzerland next month.

Arsenal have confirmed that an ankle injury sustained on international duty with England will keep Theo Walcott sidelined for between four and six weeks.

Walcott turned over on his right ankle in the early stages of England's 3-1 win over Switzerland and was stretchered off before being taken to hospital for scans on the problem.

Arsene Wenger now admits that with Nicklas Bendtner still out for "three to four weeks" and Robin van Persie absent until the end of October, his attacking options have been hit further by the loss of Walcott.

The news comes as a cruel blow to a player who has suffered extensively with injury problems in recent seasons, but had scored four goals in his past two appearances for the Gunners.

"The tackle looked quite bad," Wenger said. "When you see how it turned his ankle I thought it would be three or four days or it would be four to six weeks. Unfortunately it will be four to six weeks.

"We had some good news about the scan because at some stage we were scared it could be worse. But overall it is a question of patience and rehabilitation."

Arsenal confirmed on Tuesday that an ankle injury sustained by Van Persie in a 2-1 win over Blackburn was more serious than first feared. "That is bad news," Wenger said of Van Persie's injury. "At the start we were optimistic. Maybe a bit too much, thinking it would be one or two weeks. But the damage was bigger than expected and he will be four to six weeks."

However, Johan Djourou, Denilson and Sebastien Squillaci should all be available for Saturday's game against Bolton, while French midfielder Samir Nasri is close to returning to first-team action after undergoing knee surgery.

"He could even be involved against Bolton," Wenger said. "He has had a very good preparation and joins in [training] tomorrow. If needed I will integrate him in the squad for Bolton but for sure he will be back for our first Champions League game against Braga."
