The US Attorney’s Office for the Southern District of New York has charged the 86-year-old with 16 counts of securities fraud and three counts of conspiracy.
Prosecutors say Lewis is alleged to have used his access to confidential information to provide stock tips to individuals close to him, with the indictment referring to one girlfriend having made 849,000 US dollars (£657,000) on one of those tip-offs.
Lewis was arrested on Wednesday morning, prosecutors said. A spokesperson for the US Attorney’s Office said Lewis would appear at Manhattan Federal Court in the afternoon.
Lewis’ legal counsel David Zornow, from the Skadden, Arps, Slate, Meagher & Flom firm, said: “The government has made an egregious error in judgment in charging Mr Lewis, an 86-year-old man of impeccable integrity and prodigious accomplishment.
“Mr Lewis has come to the US voluntarily to answer these ill-conceived charges, and we will defend him vigorously in court.”
Each of the first 13 counts of securities fraud carries a maximum sentence of 20 years in prison, Manhattan prosecutors said in a statement issued on Wednesday.
The US Attorney for the Southern District of New York, Damian Williams, had announced on Tuesday that Lewis had been indicted over a “brazen insider trading scheme”.
Prosecutors said Lewis, by virtue of his investments in certain companies, received material and non-public information about these companies.
A release from prosecutors on Wednesday alleged Lewis had “misused and misappropriated this confidential information to provide stock tips to various individuals in his life, including his employees, romantic partners, and friends, as a way to provide them with compensation and gifts”.
It added: “These individuals, in turn, traded on the tips provided by Lewis for vast personal gain.”
Lewis bought a controlling stake in Spurs in 2001 for £22million.
He officially ceded control of the club last year, with Bahamian lawyer Bryan A Glinton replacing him as a director according to Companies House.
His stake in the club – which he held through the ENIC Group alongside Daniel Levy – was formally handed to a family trust last year.
Family members of Lewis remain beneficiaries of the trust.
Lewis not considered in control of Tottenham
However, the Premier League does not consider Lewis as a person with control at Tottenham, and is therefore not subject to its owners’ and directors’ test.
A Tottenham spokesperson said: “This is a legal matter unconnected with the club and as such we have no comment.”
US prosecutors said Lewis is also alleged to have falsely disclosed the extent of his ownership shares in a pharmaceutical company, Mirati, “through an elaborate array of shell companies and other entities, including an offshore trust purportedly for the benefit of his granddaughter”.
As a result of this alleged false disclosure, prosecutors said he was able to exercise warrants in Mirati that he would otherwise not have been able to exercise, “at vast financial gain”.
Also charged were Patrick O’Connor and Bryan Waugh, two pilots employed by Lewis to fly his private aircraft. In one instance, it is alleged Lewis loaned each of them 500,000 US dollars (more than £387,000) to buy shares in a company before it publicly announced favourable information about some clinical results.
Federal Bureau of Investigation (FBI) acting assistant director in charge Christie M Curtis said: “As alleged, Mr Lewis treated material, non-public information at his disposal as though it was something he could give his friends and associates for their benefit.
“This type of behaviour – blatant disregard for the law – is not only illegal but undermines the integrity of our financial markets.
“The FBI is determined to ensure that anyone willing to perpetrate insider trading schemes is held accountable in the United States criminal justice system.”
