Sources said Anwar now lives in Cliffton area of Karachi with support of Pakistan's ISI.There were rumours that Shakeel's aide Fahim Ahmed alias Machmach was also detained with Anwar, but officials denied it. Sources said Shakeel has deputed two lawyers from a Dubai law firm to get Anwar out."We hope the Interpol and CBI have got in touch with UAE authorities with regard to Anwar's detention. We have also sent an email to UAE officials to get information. Once we get confirmation, we will take out Anwar's files from the records," said a senior IPS officer from Mumbai police. In Mumbai, Anwar is wanted in around 15 cases of extortion and attempt to murder case including a plot to kill a event manager who allegedly had links with Shakeel, over a financial dispute in 2016.

"When Anwar was detained in Dubai in 2008 in a drugs case, he walked out. But things have changed a lot in recent years," the official added.Anwar used to be an estate agent until his brother got fame in the underworld after the 1993 serial blasts. Then, Anwar used to handle Shakeel's finances in Mumbai, but fled to Dubai after coming on the radar of Mumbai police.
