Khan had fled to Dubai earlier and he was arrested on landing in Delhi. A lookout circular was issued against him by both SIT and ED.
Earlier, ED had filed a case of money laundering against IMA Jewels in an alleged ponzi scam in Karnataka.
As many as 26 thousand complaints have been filed by the investors with the police against the IMA jewels’ store.
Mansoor Khan who is accused of duping over 45,000 investors has been on the run since June 7.
On Monday, he had released a video announcing his return to India in 24 hours.
Calling his decision to leave the country “a big mistake,” Khan had said that he wants to surrender and be a part of the investigation.
Mansoor Khan had also cited medical illness as one of the reasons to come back to India. Interpol had issued a blue corner notice for his lookout.
