The 73-year-old Nobel laureate will undergo investigations on Friday, the hospital's spokesperson Mohan Rajan told PTI."There was no cause for concern," he said.

The Dalai Lama was brought to the hospital in a chartered flight this evening and was admitted as he was suffering from abdominal discomfort, Rajan said. He is under the treatment of Narendra Trivedi, who is also the vice-president of the private hospital, Rajan said.

Earlier this month, the Dalai Lama had come to the hospital for a routine medical check up, hospital sources said.
