AUTHORITIES_RB2-2014A former Red Bank Regional substitute teacher, hall monitor and coach was indicted for an alleged sexual relationship with an underage student that involved sex at his Red Bank home, the Monmouth County Prosecutor’s announced Friday.

Darnell Lewis, 37, faces a four-count indictment handed down by a grand jury charging him with three counts of sexual assault and one count of endangering the welfare of a child, Acting Monmouth County Prosecutor Christopher J. Gramiccioni said in a prepared statement.

Lewis was arrested in June after authorities learned he engaged in intercourse with a 16-year-old girl at his home on Leighton Avenue, Gramiccioni said at the time. A police report gave the address as 192 Leighton.

The indictment alleges Lewis had sex with the girl on at least three occasions between December 31, 2013 and April of this year.

Gramiccioni said at the time of the arrest that Lewis had recently resigned his job at the school, where he has also served as an assistant coach for football and basketball.

Lewis is being held in the Monmouth County Correctional Institution on $200,000 bail with no 10 percent option, as set by Monmouth County Superior Court Judge Angela White Dalton, who also set no victim contact as a condition of bail.

If convicted, Lewis faces a state prison term of up to 10 years for each of the second degree charges.

The matter was investigated by detectives from the prosecutor’s Special Victims Bureau, Red Bank Police Department and the Little Silver Police Department.
