A 34-year-old man was taken into custody for questioning after he was seen taking pictures of finance minister P Chidambaram at the airport in Chennai, airport sources said on Wednesday.
They said Amir was seen taking pictures of the minister, who left for New Delhi on Tuesday, using his camera. Amir had confirmed first-class tickets to Delhi and from there to Dubai.
Initial probe revealed that Amir was one among the two persons, detained last month by CISF personnel for reportedly giving contradicting replies at the airport.
Earlier, Amir along with Mansoor, hailing from Kerala, were detained after they wanted to get off the Dreamliner aircraft ahead of its flight to Delhi. The duo reportedly gave contradictory replies when CISF sought an explanation for cancelling their journey at the last minute.
An enquiry is underway as to why he opted for a long trip to Dubai when there are direct flights available from Thiruvanathapuram and Kochi respectively to Dubai, they said.
