SO Solid Crew rapper G-Man has 126,144,000 seconds to go on a four-year jail term after being convicted of carrying a loaded pistol.

Jason Phillips, aged 24, of Westwood Park, Forest Hill, who wrote the controversial collective’s number one hit 21 Seconds, is the second So Solid Crew member to be locked up for carrying a loaded gun in public.

Phillips, who is the group’s co-leader, has worked for Government agencies trying to stamp out gun crime and break the link between rap music and firearms.

But, Southwark Crown Court heard, on November 14 last year he threw a .22 calibre modified pistol into an alleyway as he was chased by police through the West End.

Phillips had been at a PlayStation 2 premiere in Leicester Square.

Police watching CCTV spotted an “agitated” Phillips talking with bandmate Shane Neil afterwards and swooped on suspicion they were selling drugs.

As officers searched Neil, Phillips ran off and was seen “tugging desperately at his trouser pocket”.

When officers caught up with him, Phillips was unarmed and admitted he had just thrown away a £20 bag of cannabis.

He said: “It was just one spliff.” Police were led to the gun by a passer-by. It had seven live rounds.

The court heard it had been raining that night but the gun was dry when found on a pile of soaked bin bags.

Phillips claimed it was coincidence officers found the gun, but forensic tests revealed his DNA on both sides of the weapon.

After the find, officers raided Phillips’s south London flat and found three high-impact dum-dum bullets and seven unlicensed cartridges.

Phillips said he had not visited the flat for four months.

Jurors cleared him of possessing prohibited ammunition in respect of the dum- dum bullets.

But they convicted him of possessing a prohibited 9mm pistol and possessing ammunition without a certificate.

Last year, So Solid Crew member Ashley Walters, known as Asher D, was jailed for 18 months for brandishing a converted air pistol at a traffic warden.

So Solid Crew were banned from venues across the country after two people were shot during a show in 2001. In another incident a fan was beaten to death.

Three members of the band have fallen victim to violence — two stabbed and another shot.
