“He managed to insert himself into her life and the lives of other young women who would come into the office and have lunch,” prosecutor Radu Brestyan said. “He would buy them gifts and drive them home.”

Following his arrest earlier this month in New Hampshire, Leung has been held in the Merrimack County House of Corrections until the extradition process to Massachusetts could be completed. Leung was a teacher in Concord, N.H.

Police said they found he had an “alleged sexual relationship” with a minor in Concord and Newton in 2015 and 2016. The victim lived in Concord at the time and Leung was working at a summer camp in Newton at the Fessenden School.

Some of the alleged inappropriate behavior occurred while Leung was driving the victim home. “It would involve some kissing of the victim, inappropriate touching,” Brestyan said. “He grabbed her hand and put it on his genitals over his clothes.”

Prosecutors said Wednesday Leung showered the victim with gifts, including a laptop and trips. He allegedly sexually assaulted her at least 20 times over the course of two summers.

“He would go into bed and watch movies at night when he was not supposed to be in the dormitories,” Brestyan said.

According to prosecutors the girl, who was an unpaid staffer who assisted Leung at the Fessenden School, felt she had “no control” and was “degraded.”

“A lot of times he was aggressive toward her, not hitting her, but aggressively put himself upon her,” Brestyan said. “She felt degraded by him and no choice in what was going on.”

The Fessenden School fired Leung after his arrest.
