A Sea Bright man who serves as a member of the Red Bank RiverCenter board of trustees was arrested on a child pornography charge last week, according to law enforcement authorities.

Michael Warmington, 66, of Ocean Avenue, was arrested last Wednesday by detectives from the Monmouth County Prosecutor’s office.

Warmington was charged with endangering the welfare of a child by posting an image depicting the sexual exploitation or abuse of a child from his personal computer to an internet chat service on May 27, according to a warrant.

Judge Richard English set bail at $50,000, without the option for Warmington to post 10 percent. Warmington was also ordered not to have unsupervised contact with anyone under the age of 18 and not to access the internet.

The Monmouth County Correctional Institution website indicated that Warmington was still locked up Monday morning, and showed the bail amount at $100,000. A prosecutor’s spokesman did not immediately respond for comment Monday.

[UPDATE, October 18: Prosecutor’s spokesman Charlie Webster says the original bail set by Judge English was increased to $100,000 by Judge Honora Kilgallen at her discretion at Warmington’s first appearance October 13. A check of the jail website Tuesday morning showed that Warmington was no longer in custody.]

Warmington is an employee of Red Hot tourism magazine, based in Red Bank, and serves as secretary of the RiverCenter board of trustees.

[UPDATE, October 20: RiverCenter says Warmington has resigned from the board and ended his affiliation with the organization.]
