Pakistan High Commission staffer Mehmood Akhtar, expelled by India for spying, had named Samajwadi Party's Rajya Sabha MP Munavvar Saleem's personal assistant Farhat as one of his "close associates" in the crime following which he was arrested.
Farhat was picked up from Saleem's residence last night and detained. He was arrested this afternoon after prolonged questioning. This is the fourth arrest in the case.
"During Mehmood's questioning, Farhat Khan's name surfaced as one of his close associates in the espionage racket he was running along with names of some other Pakistan High Commission staffers," said a senior police officer.

A crime branch officer said Farhat's preliminary questioning has led to "certain revelations" that need to be further investigated. Names of several other people allegedly involved in the racket have cropped up.
Delhi Police is also trying to apprehend other members of the espionage ring who, it believes, were in close contact with Pakistan Mehmood Akhtar. The Pakistan High Commission staffer was caught receiving secret documents here on October 26.
Two others, Maulana Ramzan and Subhash Jangir, residents of Nagaur, Rajasthan, were held along with Akhtar. Another accused Shoaib was detained in Jodhpur and brought to Delhi by the police where he was arrested.
