The report said that Arvind Dabas, a Delhi Police constable who has been arrested, had sought Jaitley's call records for his "personal reasons".
The MHA had asked Delhi Police about the status of the case after BJP leaders Saturday accused the government of trying to gain access to Jaitely's phone call records.
According to police, Jaitley's call records were accessed by Dabas to check his communication with an unidentified man in Uttarakhand.
The man had assured Dabas that he would settle the policeman's property deal in Uttarakhand through the senior BJP leader. Dabas also runs a real estate business with two others in Uttarakhand.
He had invested in the state, but was not being able to recover the money.
Dabas had sought Jaitley's call records to check whether the man was in touch with the BJP leader.
However, when Dabas tried to access Jaitley's call records, the telecom company contacted the Delhi Police officer whose e-mail was being used for seeking Jaitley's call records, police said.
Though Jaitley has not filed a complaint, police registered a case a few days ago to ascertain whether any official had sought details about the call records or if it was a case of impersonation.
Dabas' aide Neeraj was arrested Monday. He had sought the call records of several other people from Dabas.
