An 18-year-old California man was arrested Monday after allegedly taking inappropriate photos and committing lewd acts with a 7-year-old girl at an indoor bounce house, authorities said.

Tavi Benelli, an employee at the Pump It Up Bounce House in Belmont, allegedly escorted the child to a private room before he inappropriately touched and took photos of her, the San Mateo County Sheriff’s Office said.

Benelli allegedly told the child to turn around and jump up and down as he took photos, the San Mateo Daily Journal reported. He allegedly also told her there was a dead bug on her posterior and brushed it off.

The child’s nanny reported the crime to her parents, who then told the police, the San Jose Mercury News reported.

Deputies arrived at the bounce house and interviewed Benelli. Prosecutors allege that the suspect had tried to delete photos of the child from his phone before speaking to police, the Daily Journal reported.
