A SECOND man has been quizzed by cops in connection with the nightclub attack on AJ Pritchard and his brother.

Cheshire Police said a 19-year-old man from Crewe voluntarily attended an interview under police caution as the investigation continues.

AJ, 24, was set upon by a gang of eight thugs and his brother Curtis, 23, needed knee surgery in order to save his dancing career.

The Strictly favourite said at the time his brother took the brunt of the beating to protect him.

Curtis added: “It could have been fatal.”

A 20-year-old man was previously arrested and released under investigation, but authorities have now questioned a second man over the alleged assault.

A Cheshire Police spokesperson said: "The investigation remains ongoing at this time and officers are currently following a number of lines of enquiry.

"As part of the investigation a 19-year-man from Crewe voluntarily attended Crewe Police station on Friday 25 January where he was interviewed under police caution.

"The investigation is continuing."

AJ was badly bruised but Curtis suffered a suspected broken nose, blurred vision, a split lip and a knee injury which will need surgery so he can dance again.

In an exclusive joint interview with The Sun, AJ previously said: “Curtis risked his own dancing career to save mine as he threw himself in front of the attackers so they couldn’t get to me. He was thinking of both my dancing career with my legs and my TV career with my face."

The pair had been enjoying a family Christmas at their home in Stoke-on-Trent, when they went out for the night to Nakatcha, a club in Nantwich, Cheshire.

The pair believe the attention AJ was receiving from female Strictly fans sparked a jealous rage in other men.

The investigation remains ongoing at this time and officers are currently following a number of lines of enquiry. Cheshire Police
