An Arlington karate coach who confessed to indecently assaulting a 7-year-old girl at his studio appeared briefly in court Thursday and was rescheduled for Jan. 20. 

Thomas Donahue, 52, of Lexington, is charged with indecent assault and battery on a child under the age of 14, child enticement, reckless endangerment of a child and kidnapping. He is the founder of T&P Martial Arts in Arlington, where authorities say the crime took place.

On Thursday morning, he was scheduled for a pretrial conference at Middlesex Superior Court in Woburn. He was in court briefly. Due to a scheduling conflict, the hearing was moved to Jan. 20 at 9 a.m.

Donahue was arraigned in Middlesex Superior Court on Dec 1. He was first arrested on Aug. 25, arraigned in Cambridge District Court and released on $10,000 cash bail. He was indicted by a Middlesex Grand Jury on Oct. 20.

In court Aug. 26, Assistant District Attorney Deborah Bercovitch said Donahue gave Arlington Police a “full confession” of the crime.

Bercovitch previously said the victim was watching a movie with her family when she said, “This guy reminds me of Tom. I hate Tom. He makes me touch him.”

The prosecutor said the crime would occur after the victim’s karate class at T&P. He would ask the girl to shake his genitals "to help him remove" a cast he was wearing at the time, according to Bercovitch. Once the victim would comply with the request, he would remove the cast and thank the girl, according to the prosecutor.

Donahue confirmed the prosecution’s account of the crime to police, according to the prosecution.

A parent who called Arlington Patch said the children at T&P Martial Arts were told Donahue had retired. He is, however, allowed to continue his administrative duties at the studio while children aren't present.
