Two gang members who threw ammonia at a shopkeeper and a random woman in the street are facing years in jail.

Sadik Kamara, 24 – a “rapper” who goes by the name Trizzy Trapz, and Joshua Jordan, 20, went on the rampage in Hackney on March 10 with two other gang members who are still at large.

They first robbed a family-run shop in Mare Street, where Kamara squirted the liquid at a shopkeeper, a woman in her 50s, three times.

The lone worker fought bravely and managed to hit the panic button. As she fell to the floor with burn injuries one of them stamped on her.

Minutes later they passed a woman in Hassett Road, Homerton, who was walking to a friend’s house. They forced her to the floor and pinned her face to the pavement while one repeatedly sprayed the ammonia in her face.

They then stole her handbag and ran back to their getaway car. A witness told Wood Green Crown Court during the trial that they saw the pair laughing while running along a nearby street with the woman’s handbag.

The bottles of ammonia, found dumped near the scenes, warned the contents were high strength and could cause severe skin burns and blindness. Luckily, neither victim was permanently disfigured.

Kamara, of Booth Road, Silvertown, and Jordan, of Ruscoe Road, Caning Town, were tracked on CCTV and it emerged that Kamara had received medical treatment after the attacks, saying he had burnt himself while cleaning.

He was already serving a suspended six-month sentence for possession of an offensive weapon and assaulting a police officer after being found with a knife during a stop and search.

Det Con Ben Kahane said: “The two victims in the case are hard-working, law-abiding members of the community who have endured a dreadful ordeal.

“The witness testimony describing how two of the suspects ran off laughing I think sums up the callous enjoyment the gang felt in targeting their victims.”

Kamara and Jordan were both found guilty of robbery, after having already pleaded guilty to attempted robbery.

Jordan was found guilty of two counts of applying a corrosive fluid with intent to burn, maim or disfigure or disable, or to do GBH. Kamara admitted one count of the same, and was found guilty of the other.

They will be sentenced at the same court on November 17.
