One person has been detained in connection with the twin blasts on the Delhi-Attari special express that left 67 people killed, Railway Minister Lalu Prasad said in New Delhi on Monday

"On the basis of information given by eyewitnesses, one person who was present in one of the two coaches that caught fire has been detained," Lalu told media persons after visiting the victims admitted to the Safdarjung Hospital.

He said eye-witnesses, including one of the injured, a Pakistani national Rana Shaukat Ali, had told him when he visited Panipat that two suspicious-looking persons were sitting in the coach with their faces hidden behind mufflers.

Ali lost five members of his family in the blasts.

A Railway Protection Force constable, who later succumbed to his injuries, had even questioned the duo, the minister said, adding that the whereabouts of the second person was not known.
