Fall River Mayor Jasiel Correia, who's already under indictment for wire and tax fraud, was arrested Friday for allegedly conspiring to extort hundreds of thousands of dollars in bribes from marijuana companies, according to the FBI's Boston office.

The FBI said Correia's former chief of staff, Genoveva Andrade, also was arrested on extortion and bribery charges.The office of U.S. Attorney for Massachusetts Andrew Lelling says three others were also charged. A news conference is set for 11 a.m.

Suspicions of improper marijuana licensing have been swirling around the 27-year-old Correia for at least a couple of months.

"I think it’s something we all know, but completely ignore, is the money being given to the administration by these marijuana companies for these licenses and the kickback monies that he is receiving in order to issue these licenses," Fall River City Councilor Shawn Cadime said at a public meeting in July, according to the Herald News.

Lelling's office charged Correia last fall with defrauding investors in a company the mayor founded before his election. In that case, Correia is accused of diverting hundreds of thousands of dollars of investments to finance a "lavish lifestyle" that included a Mercedes-Benz, designer clothing and adult entertainment.

He pleaded not guilty to all those charges.

Correia, a Democrat, survived a recall election in March and is on the ballot again, in a preliminary election, Sept. 17.

This is a developing story, and will be updated as more information becomes available.
