The Thai police have taken two men holding Indian passports for questioning in connection with Erawan Shrine bombing case, as they were reportedly seen "often" talking to the prime suspect--Yusufu Mieraili--until he was arrested, Bangkok Post reported.

The two were detained from their residence in Min Buri district on Sunday. They lived in Maimuna Garden Home Apartment, where the Mieraili also resided.

The police had earlier raided the housing complex on 2 September and found some bomb making materials in Room No 9106, rented out by Wanna Suansan, who has also been arrested in the case. The Muslim Thai woman was allegedly involved in Erawan Shrine bombing on 17 August as well as in the explosion at Sathon pier the next day.

Acting on a tip-off that some blast suspects were still in the building, the police raided the apartment again on 7 September. The investigators zeroed in on the two men after it was found that they had been "often" seen speaking to Mieraili.

Both the men lived together and were found to hold Indian passports. Some reports on Monday even claimed that the duo were released after questioning, however it was not confirmed yet.

The investigations on the deadly blast that killed 20 people, including several foreigners, is still in progress as the police believe that more people could be involved in the bombing plot.
