The duo, identified as G Mohammed and M Hasan, were found moving suspiciously outside the Indira Gandhi International Airport (IGIA) yesterday morning by a CCTV control room observer of the CISF.
The CCTV observer asked his colleagues on ground to intercept the duo and check their identities and that led to the recovery of Rs 3,650 and 90 Dirhams in cash, the official said.
The two, he said, told interrogators that they stole the wallet of a passenger from a DTC bus carrying passengers between terminals.
The duo have been handed over to the Delhi Police, he added.
