Spanish radio personality Eddie 'piolin' Sotelo has been taken off air amid accusations he sexually harassed a regular guest on his Los Angeles-based show.

Alberto 'Beto' Cortez, who was a writer and performer on the popular Piolin por la Manana show, which aired across America, claims Piolin "physically, sexually and emotionally" harassed him over a three-year period in a letter to radio bosses at Univision.

The radio host has denied the claims but Beto insists he has witnesses that will back up his allegations.

A statement from Piolin's lawyer reads: "A disgruntled, troubled employee has made malicious and false claims about Eddie Sotelo. This was done as part of a demand for money. The employee worked with Eddie for more than a decade. The employee's allegations of harassment... are pure fiction intended to gain a financial settlement."
