Nine members of an organised criminal network involved in conspiracy to supply cocaine and the conversion of a shotgun have pleaded guilty.

Among them is Nikhal Shastri, of Wakefield Gardens, Ilford, who admitted to possession of a firearm with intent to cause others to fear unlawful violence, possession of a prohibited weapon and conspiracy to supply class A drugs namely crack cocaine.

The 22-year-old pleaded guilty at Basildon Crown Court on Tuesday and is due to be sentenced on June 9.

Detectives executed a search warrant at NUE Prestige in Suffolk House Yard, Ashwells Road, Brentwood, in September last year and recovered a sawn stock of a shot gun and the tools use for shortening it.

At the business premises – purportedly being used as a car hire company – officers also recovered £2,600 in cash and two canisters of CS gas.

Subsequent searches revealed a loaded sawn-off shotgun and 16 cartridges hidden in the roof space of an adjoining car port.

A Turkish national, Ugar Kurkukiravul, 30, who lived at the premises, was also arrested and pleaded guilty to possession of a firearm with intent to cause others to fear unlawful violence and possession of a prohibited weapon.

CCTV recovered at the yard clearly showed him and four others handling the sawn-off shotgun earlier on the day of the arrests.
