LOS ANGELES -- A basketball and volleyball coach for the Los Angeles Unified School District has been arrested on suspicion of carrying on a sexual relationship with a female student.

Cesar Ysidro Fernandez, 39, was arrested at his home, locked up in lieu of $100,000 bail after being charged Friday with four counts of unlawful sex with a minor, police said.

The investigation began in January when investigators learned that the sexual relationship appeared to have started during the school summer break of 2009.

The student was 17 years old at the time of the relationship and is now 18, according to police.

Fernandez, a teacher at 32nd Street USC Math, Science and Technology High School, reportedly purchased expensive gifts for the teen and allegedly brought her to hotel rooms and an apartment to have sex.

According to police, Fernandez will not be put back in a Los Angeles Unified School District classroom if he bails out before the case is resolved.

Fernandez also taught summer school at Carson High School.

He has been a teacher since 1993, and has been at the 32nd Street school since 1996. It's believed he has been placed on leave pending the outcome of the case.

Fernandez is reportedly married with children.

Anyone with more information about the alleged crime was asked call detectives at the Southwest Station at (213) 485-2585 or the department's 24- hour tipline, (877) LAPD-24-7.
