Some analysts took issue with the assertion that terror groups may be involved and have a presence in Zanzibar.
Zanzibar is unlikely to have an al-Shabab or al-Qaida presence, said Ahmeid Rajab, the managing director of the Somali satellite television network, Universal TV. "After all, those radical groups never ever use acid to advance their goals," said Rajab.
Police are looking for another excuse to escape blame for failing to arrest real suspects and instead they are going after innocent people including school teachers who possess acid as part of their teaching resources, said Rajab.
Mohammed Hafidh, an economist, said he also doubts the validity of the police commissioner's statement.
He said the acid attacks do not bear the hallmarks of al-Qaida and al-Shabab attacks. The two groups are known for deadly and large-scale attacks.
The acid attacks are affecting tourism, Zanzibar's main economic activity, Hafidh, the economist, said.
Zanzibar draws visitors from around the world attracted by the archipelago's natural beauty and powdery white sand beaches. Zanzibar is also a melting pot of African, Indian and Arabian cultures and influences.
