Police are hunting a radical Muslim preacher wanted in connection with an acid attack on two British teenagers in Zanzibar.

Sheikh Issa Ponda Issa was cornered by officers near Dar es Salaam in Tanzania, but managed to escape and is now on the run.

He was hit in the shoulder with a tear-gas canister during the altercation, according to local police in Morogoro – the scene of the clash.

Police commander Faustine Shilogile said: “He has not been arrested. He has been shot at. We have been looking for him in all corners of the country.”
He added: “We are no closer to finding who was responsible for this. But this is a serious police investigation, and we are doing everything we can.”

Five men are also being questioned by officers, according to the authorities.

Victims Katie Gee, and Kirstie Trup, both 18 and from London, are still being treated for burns at Chelsea and Westminster Hospital after arriving home on Friday.
They are said to be “well rested and comfortable”.
A hospital spokesman said: “They have been with their families all day. Doctors are continuing to assess treatment options for both patients.”
The pair were attacked by men on a motorbike as they walked across a road on Wednesday night.
They had been nearing the end of a trip working as volunteer teachers on Zanzibar, a predominantly Muslim island in the Indian Ocean.
Witnesses have spoken of their desperate attempts to wash the acid off the two girls before they were rushed to hospital.
A picture released by the teenagers’ families shows one appears to have extensive acid burns on her chin, neck and upper chest.

It is thought one of the girls is not as badly injured as the other because she was helped into the sea immediately after the attack.
They had apparently been due to return to the UK to collect their A-level results next week.
Miss Trup is hoping to study history at the University of Bristol and Miss Gee is considering the University of Leeds, according to reports.
Meanwhile, Tory MP Bill Cash, who sits on the all-party parliamentary group for Tanzania, has urged the Foreign Office to further upgrade its travel warning for tourists visiting both Zanzibar and Tanzania because it was “more than just an ordinary criminal event”.

The Foreign Office updated its Tanzania travel advice page on Friday with details of the attack and warns British nationals to “take care” and read its travel advice.
Mr Cash said: “People need to be extra vigilant and the Foreign Office and High Commission need to make a very thorough evaluation of the threat, as these latest attacks would seem to be on religious grounds.
