The Ministry of Foreign Affairs today summoned Indian Deputy High Commissioner Pawan Badhe following the return of Prime Minister's Policy and Strategy Affairs Adviser Dr Zahed Ur Rahman from Delhi airport.

The Indian diplomat was called in to discuss the matter, according to a foreign ministry official.

"He was summoned this afternoon to discuss the issue," the official told this correspondent.

Dr Zahed was stopped at Delhi airport by Indian immigration authorities yesterday evening after his name was flagged during a security check.

Quoting sources, Indian news portal CNN-News18 reported that Zahed was “briefly stopped” as his name reportedly appeared on a security-related watchlist.

“After intervention, the immigration authorities allowed his entry, but the adviser decided to return home,” a source in New Delhi told The Daily Star.

On Sunday afternoon, Bangladesh High Commissioner Riaz Hamidullah went to Delhi’s Indira Gandhi International Airport to receive him.

According to diplomatic sources, Zahed was travelling to India to attend the 28th Meeting of the Committee of Senior Officials (CSO) of the Indian Ocean Rim Association (IORA), scheduled for June 15 and 16 hosted by the Indian Ministry of External Affairs.

However, after landing, he was questioned by Indian immigration authorities and kept waiting for about two and a half hours without showing any specific reason, Prothom Alo reports.
