Has sought, sought

ith FBI now confirming that Headley was in touch with Lakhvi, the NIA has sought the voice tapes of their conversations to match the same with the intercepts of the conversations between the 26/11 attackers and their Pakistan-based handlers. This would help nail Lakhvi as the key strategist behind the Mumbai strikes.
Though India has, in its set of dossiers to Pakistan on the 26/11 probe, sought the voice samples of Lakhvi, the authorities in Islamabad are yet to heed the request.
During the FBI team’s visit here, India also sought the US agency’s help to get Pakistan to question the 26/11 accused arrested on its soil to confirm Headley’s presence in the LeT control room at Karachi during the Mumbai mayhem.

Headley, the agencies here suspect, was working as an undercover agent for the US agencies to keep track of the drugs trafficking trade through Pakistan and Afghanistan, only to later turn rogue in 2005.

I just wonder what they mean by "has sought" and "sought". Do they mean "has been seeking voice taps still"? or Do they mean "already got the voice taps"?
