Allen Weisselberg, the former chief financial officer of the Trump Organization, was freed from custody on Wednesday, according to the New York City Department of Prison.

Weisselberg was detained on January 10 at Rikers Island in New York after assisting in the design of a complex, 15-year tax fraud scheme at the family firm of former president Donald Trump.

He was sentenced to five months behind bars but was eligible for release after 100 days with time off for good behavior.

Weisselberg, 75, pleaded guilty last year in connection with the long-running scheme. He and other executives received bonuses and perks in ways that cheated tax authorities and saved the company money. He evaded taxes on $1.76 million of income.

As part of his plea deal, Weisselberg testified at last year’s trial of the Trump Organization, which also was charged with the tax fraud scheme. The company was found guilty and fined $1.6 million, the maximum allowed.

A lawyer for Weisselberg did not immediately respond to a request for comment.
