SPRINGFIELD — Members of an FBI gang task force burst into a home on Firglade Avenue at 4 a.m. on Dec. 5, with reputed Latin Kings East Coast leader Michael Cecchetelli in the crosshairs.

They made that arrest, but also found a loaded gun at his uncle David Cecchetelli’s bedside and more bullets under the mattress frame, according to records filed in U.S. District Court. The men were roommates.

Consequently, agents made a second, unexpected arrest that morning. Michael Cecchetelli was charged in a sweeping indictment for a racketeering conspiracy involving dozens of reputed Latin Kings leaders and associates, while his uncle caught a stray bullet of sorts. David Cecchetelli was charged through a criminal complaint for being a previously convicted felon in possession of ammunition.

In addition, an analyst with the Bureau of Alcohol, Tobacco, Firearms and Explosives is conducting a trace of the Smith & Wesson .357-caliber five-shot revolver to see whether the weapon crossed state lines, according to an affidavit in support of a criminal complaint against David Cecchetelli.

The 52-year-old was held over the weekend at a state prison in Norfolk, but was released on $10,000 unsecured bond after a court hearing in Boston Monday afternoon. A federal magistrate judge ordered him to find a new place to live and stay away from members of organized crime groups and the Latin Kings, according to his attorney.

“We are very pleased the court granted David Cecchetelli pretrial release. He appeared in court today supported by family members and friends,” said Springfield attorney Daniel Hagan.

Cecchetelli — who has historical ties to the local faction of the Genovese crime family and a previous bookmaking conviction — had managed to stay out of trouble since his release from federal prison in 2007. He has reinvented himself as a social media personality and has starred in a yet-to-be-released independent TV series called “The Flanagans,” an Irish crime family drama, according to supporters.

Cecchetelli bills himself as “chickytheginni” on social media and favors colorful clothing — with a particular penchant for flashy velour track suits, thick-rimmed glasses and heavy gold chains.

Court records suggest he was caught unawares by last week’s raids, which unfolded across the state and netted more than 60 arrests.

Cecchetelli told agents he had been awake watching television in his room, and asked a Springfield police officer involved in the raid to get his clothes and sneakers from his bedroom. He said he was a part-time housemate with his nephew and split his time between there and his girlfriend’s apartment in Westfield, but the couple had recently been on the outs.

“He stated that due to his strained relationship with his girlfriend he was spending more time at the premises,” the sworn statement reads.

Task force members found four rounds of ammunition in a box under Cecchetelli’s bed, plus a loaded revolver tucked behind a tabletop fan on his dresser, according to court records. Cecchetelli had pictures of himself around the room, the affidavit reads.

Cecchetelli has been charged with the weapons violation separately, and is not a part of the racketeering indictment that ensnared his nephew. Michael Cecchetelli had previously been identified as a statewide leaders of the Latin Kings in 2006, when he was convicted of an illegal gun charge. He rocketed up the gang hierarchy after his release from prison in 2009, according to investigators.

The FBI’s “Operation Throne Down” was billed as a historic upset for the gang, whose exploits in Massachusetts included alleged murder plots, drug trafficking, assaults and gun-running, with Michael Cecchetelli at the helm.

For his part, David Cecchetelli was sentenced to eight months in prison after pleading guilty to conducting an illegal gambling business in Springfield in 2005. That conviction earned him “prohibited status” to possess a firearm or ammunition under federal law.
