Coimbatore: The National Investigating Agency (NIA) carried out searches at various places in Coimbatore on Wednesday.
According to the NIA reports, some people are in touch with those involved in the Easter day church blasts in Sri Lanka.
Raids were conducted by a team of NIA sleuths at seven places in the city.
This raid was conducted on the basis of inputs that certain people are reportedly in touch with those behind the Easter day attacks on social media, police sources said.
The searches were a continuation of those conducted here and in Kerala in connection with an ISIS terror module, they said.
The IS had claimed responsibility for the serial bombings in Sri Lanka and around nine suicide bombers were involved in the attack.
The Sri Lankan government has said that local terror group National Towheeth Jamaat (NTJ) carried out the attacks with support from the IS.
A series of eight blasts rocked the capital of Sri Lanka on 21 April in the morning, destroying three churches and as many five-star hotels while the seventh and the eighth explosions happened at noon.
At least 253 people had been killed in the blasts while around 400 are injured in the terrorist attack. Among those dead were 35 foreigners.
The first blast occurred in Colombo inside the St Anthony Church. The second bomb exploded in the Sebastian Church of Negombo outside the capital. The third blast occurred in the church of the eastern city of Batticaloa.
Terrorists targeted three hotels too: The Shangri La, The Cinnamon Grand, and The Kingsbury.
The seventh bomb went off in front of the hotel of Dehiwala in Colombo. The eighth blast happened in Colombo again.
A two-member NIA team headed by an Inspector General had left for Colombo last month to coordinate with the Sri Lankan authorities in the investigation into the attacks. “We have our own FIR against ISIS modules. The visit is not to assist Sri Lanka with their probe but to see if an exchange of information and evidence gathered by us and them can be mutually beneficial,” a top NIA official had then said.
