Michael O'Donnell/VentureBeat Zain Jaffer, who founded mobile ad firm Vungle and was its CEO until this week, was arrested Tuesday on charges of attempted murder, lewd act upon a child, and other related charges.

On Thursday, the San Francisco-based maker of a video ads platform announced that the board of directors had placed Jaffer on an indefinite leave of absence for personal reasons. It replaced Jaffer as CEO with Vungle chief operating officer Rick Tallman.

The first details of the arrest for 29-year-old Jaffer surfaced on Friday.

San Mateo County records show he was arrested on charges of attempted murder, assault with a deadly weapon, child abuse, battery upon an officer and emergency personnel, lewd act upon a child, and oral copulation with a person under 14.

As part of the announcement on Thursday, the company said that Vungle’s board voted to replace Jaffer as CEO immediately after being informed of personal issues unrelated to his employment, though no other details were provided. On Friday, after we got in touch about the arrest, the company had more to share.

“While we do not have any information that is not in the public record at this point, these are extremely serious allegations, and we are shocked beyond words,” a Vungle spokesperson told VentureBeat on Friday. “While these are only preliminary charges, they are obviously so serious that it led to the immediate removal of Mr. Jaffer from any operational responsibility at the company. The company stressed that this matter has nothing to do with Mr. Jaffer’s former role at the company.”

We have reached out to Jaffer for comment and will update you if he responds. He is set to appear in court on November 1.
