Phil Breckon, eastern regional manager, said: “This is a shocking incident that should never happen.

"Our charity believes in safe streets and safe communities and we hope that these rewards and our appeal will help to bring about justice.

“We are appealing to anybody with any information on the whereabouts of Nana Oppong, Temitope Adeyinka and Israar Shah to do the right thing and to tell our charity what you know, 100 per cent anonymously.

"What you tell us can make all the difference in keeping others safe from harm and no information is too insignificant to tell us.

“Our charity knows it can be hard to give information about somebody you know, however it is important to remind people that assisting a person wanted for questioning over a crime can lead to prosecution.

"You can speak to us anonymously by calling our UK Contact Centre which is open 24/7 on freephone number 0800 555 111 or you can use our simple and secure anonymous online form."
