Harris Wittels, who worked as a writer and executive producer on the US TV comedy Parks and Recreation, was found dead of a possible drug overdose at his Los Angeles home. He was 30.

His assistant found him at his home in the Los Feliz area around noon, and he was pronounced dead at the scene, police officer Rosario Herrera said.

She said the death is being investigated as a possible drug overdose but the Los Angeles County coroner’s office will determine the exact cause.

Wittels had talked about his struggles with drug abuse in a podcast last autumn.

He was a co-executive producer and writer with occasional acting appearances on Parks and Recreation, and his death comes just a few days before the series finale of the seven-season comedy starring Amy Poehler.

He performed stand-up comedy and wrote for other TV shows including The Sarah Silverman Programme and Eastbound & Down.

Wittels also popularised the term ‘humblebrag’ with his Twitter account of the same name, which eventually became the book Humblebrag: The Art of False Modesty.

He used it to mock celebrities and others who masked their braggadocio in self-deprecation.
