CHENNAI: Tamil Nadu Chief Minister J Jayalalitha has sought Prime Minister Narendra Modi's help to trace Raghavendran Ganeshan, an Infosys employee who has been missing since Tuesday’s bomb blasts in Brussels. She appealed to Modi to direct the Ministry of External Affairs (MEA) and the Indian Embassy in Belgium to provide help to the family of the Tamil Nadu resident.

"I write to bring to your urgent attention the case of Thiru Raghavendran Ganeshan, a native of Tamil Nadu who is currently listed as missing in the recent bomb blasts in Brussels, Belgium. Thiru Raghavendran Ganeshan is the eldest son of his parents who hail from Tamil Nadu. His young wife, who is also from Tamil Nadu, is currently living in Chennai, after delivering the couples' first child. The whole family is extremely anxious to hear word of him and to know about his whereabouts and safety. They have appealed to me to help trace their son," She wrote.

"I request you to kindly instruct the Ministry of External Affairs and the Indian Embassy in Brussels to provide the family all necessary assistance to trace Mr. Raghavendran Ganeshan at the earliest. This assistance would be of great help and solace to the very worried family," she added.

Raghavendran Ganeshan's phone call records indicate that he was travelling in the city metro at the time of the explosions. There are unconfirmed reports of his friends getting messages from him on the social media that he is safe.

“We have tracked his last call in Brussels. He was travelling in the metro rail,” External Affairs Minister Sushma Swaraj tweeted on Thursday even as the Indian mission in Brussels continued its efforts to locate him. Earlier Sushma Swaraj had also spoken to Ganesh's mother Annapoorani Ganeshan living in Mumbai. His mother had talked to him a while before the blast. Ganeshan’s wife and son are in Chennai.

Raghavendran’s younger brother Chandrasekar Ganeshan, who works as a software engineer in Germany, has reached Brussels to join the search operations. Raghavendran has been working for a Belgian telecom firm for the past few years.

According to his family sources, the Infosys engineer was at the Montgomery metro station just before 9 am on the fateful day. The blast at the Maelbeek Metro Station that falls after Montgomery occurred a little after 9 am. The blast at the station that followed the terror attacks at the airport killed 20 people.

Around 200 injured people are in various hospitals and they have not been identified or their identities not yet disclosed by the hospital authorities. Hundreds of passengers are still stranded at the airport because of security checks. The Zaventem airport is yet to be reopened.

Two Jet Airways crew members were also injured in the explosions at the airport. According to Sushma Swaraj, they are recovering. Meanwhile, the Indian Government is coordinating with Jet Airways to evacuate the stranded Indian citizens.

Meanwhile, the Belgian Police on Saturday arrested six people in connection with airport and metro suicide bombings in Brussels. Two others were arrested in the Belgian capital and one person was arrested in Jette on the city's outskirts earlier.
