The Australian Federal Police on Wednesday said investigations into the case of Indian doctor Mohamed Haneef are ongoing and it is still potentially possible that a brief of evidence will be submitted against him.
The Indian doctor returned to India at the weekend after prosecutors dropped a charge against him that he had recklessly provided support to a terrorist organisation by having given his mobile phone SIM card to a relative linked to the foiled UK terror plot.
"The investigation is far from complete," Australian Federal Police Commissioner Mick Keelty said about the probe into the case of Haneef.
"It is still potentially possible that a brief of evidence will be submitted against Dr Haneef," he added.
He said a mobile phone SIM card central to police investigations into Haneef was in the vicinity of both failed bomb plots in both London and Glasgow.
Australian prosecutors' claims the SIM card was found in a burning jeep used in a terrorist attack on Glasgow Airport on June 30 later proved to be a mistake, as it was in fact found in searches at Liverpool, 250 kms away.
Keelty told reporters in Canberra that while there had been much conjecture about the SIM card, it had been in the vicinity of both bomb plots, although he did not explain further.
