Last night (28 August), Abz took to the social networking site and confirmed he is no longer part of the boyband before thanking fans for their support.
Abz did not, however, give an explanation for his departure from the group. He simply said: "As of today I am no longer a member of @Official5ive. Thank you to all the fans who supported, I love you all."
The news came as a shock to fans, but more so for his fellow bandmates - Scott Robinson, Sean Conlon and Ritchie Neville - who were expecting Abz to join 5ive for a gig in Holland this weekend.
Scott replied: "@abzlove wow that's really sad to hear especially on Twitter. Wish you would have called me. I take it you're not coming to Holland #Shocked."
@abzlove thanks for the heads up via twitter.— Ritchie Neville (@RitchieNeville) August 28, 2014
Clearly annoyed, Ritchie also tweeted: "@abzlove thanks for the heads up via Twitter." Sean, meanwhile, stressed to fans that he was as confused about Abz's decision as they were.
He said: "Don't understand it, but I respect @abzlove decision, don't understand what's gone on but [he will] always be welcomed back, as I'm sure he will be when he's had break."
5ive - originally made up of Abz, Scott, Ritchie, Sean and Jason 'J' Brown - found fame in the 90s and found worldwide success with hits such as 'Slam Dunk' and 'When The Lights Go Out'.
In September 2001, the group split, however they were given a second shot on ITV2 show The Big Reunion last year. J decided not to take part.
Earlier this year, it was revealed that Abz would not be joining his three bandmates on the 'Big Reunion Boyband Tour', which kicks off in October.
At the time, the group insisted that Abz had not left 5ive and tweeted: "Bad news guys, there is a bad rumour spreading! Good news it's not true! Abz ain't leaving the band!"
It was said that Abz was unable to agree to all the terms and conditions of the tour so decided to give it a miss.
