IRWINDALE >> Prosecutors Thursday filed several sex charges against a former Irwindale police officer who allegedly molested a 14-year-old Explorer Scout. The officer was arrested Wednesday.

Daniel R. Camerano, 27, is accused of using a minor for sex acts, sending harmful matter, oral copulation of a person under 16, sexual penetration by a foreign object and two counts of contact with a minor for sexual offense, according to officials with the Los Angeles County District Attorney’s Office.

Sheriff’s deputies arrested Camerano Wednesday morning. He was released from custody in lieu of $240,000 bail.

Camerano is expected to be arraigned July 15 at the Clara Shortridge Foltz Criminal Justice Center.

The alleged crimes began in May 2009 and continued through November 2012, according to the felony complaint issued by the D.A.’s office.

Camerano was an advisor to the Police Department’s Explorer Scouts Program.

He allegedly began a sexual relationship with a 14-year-old girl in the program and sent sexually suggestive text messages to another female Explorer, according to a press release from the D.A.’s office.

Police Chief Anthony Miranda said Camerano resigned from the department Tuesday. Camerano had been with the department for eight years. He was placed on paid administrative leave amid allegations he had inappropriate relationships with Explorer Scouts.

If Camerano is convicted, he must register as a sex offender and faces up to five years, four months in state prison.

Camerano is one of several Irwindale police officers who have recently been criminally charged or who are under investigation.

Former police Sgt. David Fraijo was arrested in March on charges of kidnapping to commit another crime, forcible oral copulation, oral copulation under the color of authority, sexual battery by restraint and assault by a public officer.

Fraijo is accused of sexually assaulting a woman in 2012 during a traffic stop. The victim agreed to a settlement with the city for $400,000 in damages after she had initially filed a $20 million civil lawsuit.

In a 2013 case, former police officer Dennis Alva was sentenced to one year in county jail and five years probation for stealing his 89-year-old father’s life savings of $250,000.

Alva, 48, surrendered to deputies and pleaded no contest to one count of grand theft.

Two lawsuits have been filed against Officer Mario Camacho, a former lieutenant. A suit filed by Officer Rudy Campos claimed Campos didn’t get overtime and got bad performance evaluations after he voted against a contract item Camacho favored.

Another lawsuit filed claimed Camacho sexually harassed a non-sworn police cadet.

The city’s insurance provider Joint Powers Insurance Authority pointed to these allegations of corruption in the Police Department as an area of concern when it placed the city on a Performance Improvement Plan last fall.

JPIA officials said the PIP was implemented due to a series of alleged misconduct and reports of criminal behavior against the police officers as well as criminal public corruption charges against city officials related to lavish trips taken to New York City, where officials spent $200,000 in public funds on expensive hotels and restaurants, limousine services and entertainment.
