Raj who?

Eight years after his $70 million insider trading trial shook Wall Street, former Galleon Group founder Raj Rajaratnam is back in town — and trying his best to go unnoticed.

“Oh no, not me,” Rajaratnam, 62, told a photographer who spotted the fallen hedgie escaping his $17.5 million Sutton Place apartment on Thursday and called his name.

The denial was futile, however, as the ex-billionaire — who was leaving through a side-door service entrance — looks just as he did 11 years ago, right down to his slicked-back hair, mustache and slight limp.

Sporting a brand new iPhone, an olive golf shirt, tan pants and leather satchel, the trader-turned-convicted felon seemed to be without a care in the world as he waited near a Sutton Place doorway on 54th Street for his driver, who whisked him away in a dark blue Audi Q5 SUV.

Rajaratnam — who’s still required to check in with federal prison officials in Brooklyn — has tried to keep a low profile since he was released from federal prison in July. Staff at 60 Sutton Place were given stern warning in an e-mail to not talk to the media about the disgraced resident, one building employee told The Post.

Rajaratnam was released from prison more than two years early thanks in part to the First Step Act, a series of criminal justice reforms that President Trump signed into law last year after Kim Kardashian lobbied for it. He had originally been sentenced to 11 years behind bars following a seven-week insider trading trial that resulted in him being found guilty on all 14 counts of conspiracy and securities fraud.

The founder of Galleon Group, who was reportedly worth about $700 million in 2010, had been confined to a wheelchair during his stint at the top floor of the Federal Medical Center in Devens, Mass., a minimum-security section of the federal prison overlooking Mirror Lake outside Boston, The Post has reported.

There, he was pushed around by a “manservant” and was on dialysis for his diabetes, according to earlier Post reports.
