MONTEREY PARK >> Police on Monday arrested a Schurr High School tennis coach who was accused of having a sexual relationship with one of his players, authorities said.

Monterey Park Police said Van Phuoc “Timothy” Dang, 26, of West Covina, is being held at the city’s jail on $100,000 bail.

Police said Dang began the relationship with the student when she was 14 years old, soon after he started as a coach at the school. The relationship continued for three years.

Monterey Park Police Lt. Bill Cuevas said the victim, now 17, on Monday morning told a school resource officer for the Montebello Unified School District about the relationship.

After trying to investigate the victim’s claims, the school resource officer notified Monterey Park police, who found that the crimes occurred off campus.

“We conducted our own investigation, and determined that the crimes occurred in Monterey Park,” Cuevas said.

“He coerced her into the relationship,” he continued.

Cuevas said Dang has been listed as a Schurr High tennis coach for three years, and previously worked as a coach for El Monte High School.

Cuevas said police received information indicating Dang also at one point worked as a private tennis coach in Temple City.

The superintendent of the Montebello Unified School District said Tuesday that Dang was fired after the allegations were revealed.

“The coach’s employment with the district has been terminated,” Superintendent Susanna Contreras Smith said in an email.

She said the school district is “working closely” with Monterey Park Police as they conduct their investigation.

“The safety and security of our students is and always will be our top priority,” Smith said.

Several San Gabriel Valley school districts have been recently hit with incidents of inappropriate relationships and abuse by teachers on their students.

In August, Richard Paul Daniels, 57, a former Arroyo High School teacher, was sentenced to three years in prison for having a sexual relationship with a 15-year-old student three years ago.

Former Mark Keppel High School girls basketball coach Joe Kikuchi was charged in October with 24 counts of sexual abuse and child molestation after police arrested him on suspicion of abusing one of his 15-year-old players.

Dang was arrested on three felony counts, including lewd acts with a minor and sex with a minor where the suspect is over 21 years of age, authorities said.

He is scheduled to be arraigned in Alhambra Superior Court on Wednesday.

Investigators said they believed there could be other victims, but have not identified any yet.

Anyone with more information is encouraged to call the Monterey Park Police Department Investigations Bureau at 626-307-1236 or their local police department.
