Amid a swell of criticism over domestic violence allegations against founder and CEO Gurbaksh Chahal, ad tech company RadiumOne said on Sunday that it had replaced Mr. Chahal as CEO. Bill Lonergan, chief operating officer, was named to succeed him.

"At a board meeting yesterday evening, RadiumOne's board of directors voted to terminate the employment of Gurbaksh Chahal as CEO and Chairman of the company," the company said in a statement confirming a report by Re/code. "Bill Lonergan, the company COO, will take over as CEO of the Company immediately. Bill has an extraordinary professional background and has helped build Blue Lithium and RadiumOne into industry leading brands. We are confident he will continue Radium One's impressive trajectory."

The company had come under increasing fire after Mr. Chahal reportedly pleaded guilty to two misdemeanor battery charges related to allegations that he had assaulted his girlfriend.

Attempts to reach Mr. Chahal for comment Sunday through the company, his attorney and LinkedIn were unsuccessful.
