Kevin P. Carmichael, 40, of Millis was arrested Saturday after going to the Braintree police station to talk with detectives, Police Chief Russell Jenkins said in a press release.
Carmichael opened Masters Self Defense on Quincy Avenue in 2003, and teaches in the nonprofit Braintree After School Enrichment Program (B.A.S.E.). The program is not affiliated with the town school district.
Jenkins said the alleged assault did not take place at B.A.S.E. A spokesman for the program could not be reached for comment Sunday.
Carmichael is charged with indecent assault and battery on a child under 14.
He was being held on $25,000 cash bail pending his arraignment Monday in Quincy District Court.
Jenkins said police first learned of the assault Friday and immediately began an investigation.
Carmichael agreed to talk to detectives at the police station, where he was arrested, Jenkins said.
According to his website, Carmichael began studying martial arts in 1987 and received his black belt in 1998.
In 2003, he opened Masters Self Defense Center at 197 Quincy Ave. His website states Carmichael has taught at more than 42 after school-programs in the Massachusetts area.
