A man has been jailed for his part in a huge drug gang responsible for flooding a London borough with heroin and crack cocaine.

Salikul Islam, of Singlewell Road, Gravesend, was sentenced at Snaresbrook Crown Court after admitting supplying both Class As.

He was jailed along with two fellow members of the racket.

So far, 37 people have pleaded guilty to 70 offences.

Of these, 27 have been sentenced to a total of more than 80 years behind bars.

More than 300 officers were involved in the raids on 50 properties where in excess of £60,000, half a kilo of drugs and four stun guns were found following a four-month surveillance operation.

Islam, 22, is now beginning a stretch of two years and four months, while fellow dealers 21-year-old Taukir Ahmed, of Tower Hamlets, and Muhammed Ali Hasan, 25, of no fixed address, both received two years and eight months.

Ten men pleaded not guilty to drug offences at the court and will appear in court for trial later in the year.

Six more will be sentenced later in the month.

Islam is believed to be the only person from Kent convicted of being involved in the drugs ring, with the vast majority living in Tower Hamlets.
