Sri Lankan authorities have arrested a Saudi-educated scholar for what they say are links with Zahran Hashim, the suspected ringleader of the Easter Sunday bombings, throwing a spotlight on the rising influence of Salafi-Wahhabi Islam on the island's Muslims.
Mohamed Aliyar, 60, is the founder of the Centre for Islamic Guidance, which boasts a mosque, a religious school and a library in Zahran's hometown of Kattankudy, a Muslim-dominated city on Sri Lanka's eastern shores.
"Information has been revealed that the suspect arrested had a close relationship with ... Zahran and had been operating financial transactions," said a police statement late on Friday.
The news comes as Catholic Churches held the first regular Sunday Mass since the Easter suicide bombings that killed more than 250 people.
The police statement said Aliyar was "involved" with training in the southern town of Hambantota for the group of suicide bombers who attacked hotels and churches.
A police spokesman declined to provide details on the accusations.
Calls to Aliyar and his associates went unanswered. Reuters was unable to find contact details for a lawyer.
The government says Zahran, a radical Tamil-speaking preacher, was a leader of the group.
Two Muslim community sources in Kattankudy told Reuters his hardline views were partly shaped by ultra-conservative Salafi-Wahhabi texts that he picked up at the Centre for Islamic Guidance's library around 2-3 years ago. The sources are not affiliated with the centre.
"I used to always run into him at the centre, reading Saudi journals and literature," said one of the sources.
During that time, Zahran started criticising the practice of asking God for help, for instance, arguing that such pleas were an affront to pure Islam.
"That kind of teaching was not in Sri Lanka in 2016, unless you read it in Salafi literature," the source added, requesting anonymity to avoid repercussions in Kattankudy.
Salafism, a puritanical interpretation of Islam that advocates a return to the values of the first three generations of Muslims and is closely linked to Wahhabism, has often been criticised as the ideology of radical Islamists worldwide.
Wahhabi Islam has its roots in Saudi Arabia and is backed by its rulers, although Crown Prince Mohammed bin Salman has committed the kingdom to a more moderate form of Islam.
Other than the fact that Zahran visited the centre, the sources in Kattankudy said they did not know of any personal ties between him and Aliyar.
