"We recorded statements of these officials today. They are the same officers who had met Borge," a senior Railway official told PTI.
The three persons questioned were ADAG security officer and former DGP, K K Kashyap, retired assistant commissioner of police, Shailesh Kale and ADAG's aviation security officer and retired wing commander, Sawla.
Borge, who found the pebbles and gravels in the fuel tank of Anil Ambani's helicopter had referred to Reliance officials meeting him in his letter.
The letter said that Reliance officials had met Borge and asked his telephone numbers.
Railway police said the three officials, whose statements were recorded today, had reportedly met Borge at the Air Works hanger at Kalina on April 27, a day before his death.
