A police chief under fire for his handling of anti-Latino abuse allegations that led to the arrests of four officers last week is retiring from office, the mayor said Monday.

Leonard Gallo, chief of the East Haven Police Department, has been chastised by federal civil rights investigators for creating a hostile environment for witnesses, and his lawyer has acknowledged that last week's indictment refers to him as an unnamed co-conspirator.

Gallo, 64, had been suspended as police chief in April 2010 after the FBI launched the criminal investigation, but he was reinstated to the post in November after his friend Mayor Joseph Maturo Jr. took office.

Maturo said Gallo's retirement, which takes effect Friday, is "a unique opportunity to provide new leadership and the healing necessary given recent events."

The four officers, who were arrested Jan. 24 by the FBI, are accused of waging a campaign against Latino residents that included beatings, false arrests and harassment of those who threatened to report misconduct. They face charges including deprivation of rights and obstruction of justice; all of them have pleaded not guilty.

Frederick Brow, chairman of the town's police commission, said Monday that the commission was preparing to vote Tuesday night on whether to recommend to the mayor that Gallo be fired. He said he believes Gallo should be dismissed.

"It's been a general breakdown in control in that department for quite a while and it's time for Gallo to be terminated," Brow said.

The FBI also is targeting additional suspects, and state officials say they are preparing for the possibility of widespread arrests that could cripple the town's police department.

The federal indictment refers to Gallo as co-conspirator 1, accusing him of blocking efforts by the police commission to investigate misconduct. Gallo's attorney, Jon Einhorn, has denied those allegations.

Einhorn said Gallo is retiring because he does not want to be a distraction for the town, and his departure is not an admission of guilt. He said Gallo is the target of a lawsuit and could face charges in the criminal probe. He said his client will be vindicated and he does not believe criminal charges would be justified.

Maturo is also facing heavy criticism for saying last week that he "might have tacos" as a way to do something for the Latino community. He later apologized for the remark.
