A 46-year-old private tennis coach was charged Wednesday with nearly two dozen counts of having sex and engaging in a sex act — some of which occurred at Scholl Canyon Golf and Tennis Complex — with a 15-year-old apprentice, police said.

Coach Dale Kim, a married Northridge resident, faces 10 felony counts of committing lewd acts on the 15-year-old Granada Hills girl from June 1, 2011, to April 5 this year, according to a Los Angeles County Superior Court complaint.

Kim is also charged with seven felony counts of oral copulation of a minor, two felony counts of unlawful sexual intercourse and two felony counts of sexual penetration with a foreign object, according to the complaint.

Glendale police on Monday picked Kim up at the tennis complex and arrested him on suspicion of sexual acts with the girl, who reported the allegations to police.

“She realized the whole situation had gone way too far,” Glendale Police Sgt. Tom Lorenz said.

Kim — who police say was her coach for several years — rented courts at the Glendale complex for her lessons, Lorenz said.

At some point, he offered her massages, which allegedly led to him touching her body in a sexual manner, Lorenz said.

Their interaction allegedly progressed to fondling, which police say occurred in Kim's vehicle in the tennis complex parking lot.

Eventually, Kim allegedly took the girl to a motel in Tujunga, where they engaged in sexual intercourse, according to police.

Several months later, the girl notified police about her alleged relationship with Kim.

Kim was charged and acquitted of sexual battery in January 1998, according to Los Angeles County Superior Court records.

Glendale police are still trying to determine how many students Kim instructed, Lorenz said.

Detectives are asking anyone who has any information about Kim — or a potential victim — to contact them.

He was being held in police custody Wednesday in lieu of $875,000 bail.
