One person who allegedly maintained connections with the four Sri Lankans arrested in India on suspicion of having links with ISIS was arrested in Maligawatta.

The Criminal Investigation Department says the suspect named Amir, was arrested in Colombo.

Inspector General of Police Deshabandu Tennakoon appointed a committee to investigate the four Sri Lankans linked to ISIS arrested at the Ahmedabad Airport in India.

Police Spokesperson DIG Attorney at Law Nihal Thalduwa says the committee will be chaired by the DIG of the Criminal Investigation Department and the Director of the Police Terrorism Investigation Division.

Four ISIS terrorists were arrested in Ahmedabad on Monday (20), days after the city airport received a bomb threat.

The terrorists - believed to be Sri Lankan nationals - were arrested by the Gujarat Anti-Terrorism Squad after a tip-off.

Vikash Sahay, Director General of Police, Gujarat, said these four terrorists had boarded an IndiGo flight bound for Ahmedabad from Chennai on Monday (20).

The arrests were made after checking the list of passengers coming from the Southern region and getting their identities confirmed by officials in Colombo.

Officials said the suspects - Mohammad Nusrat, Mohammad Farish, Mohammad Nafran and Mohammad Rashdeen, are aged between 27-43 years.

The Criminal Investigation Department says one of the suspects is a resident of Negombo, while the others are from Colombo and surrounding areas.

The CID says the Terrorism Investigation Division is also investigating the incident.
