US celebrity judge and social media star Frank Caprio has died aged 88, his family has said.

Over a 40-year career in Rhode Island, he famously used compassion and humour to make judgements that took into consideration the personal circumstances of the people in the dock.

Videos of Judge Caprio presiding over cases on his hit TV show Caught in Providence have had billions of views on social media, earning him the title the "nicest judge in the world".

His death following a diagnosis of pancreatic cancer was announced on his official Instagram account, where he was remembered for his "warmth" and "unwavering belief in the goodness of people".

Judge Caprio had presided over thousands of cases in his hometown of Providence, Rhode Island, before embarking on a TV career.

His signature courtroom style produced viral clips ranging from him inviting children to sit with him behind the bench during cases, to announcing a "mini-judge" soft toy of himself.

A TikTok video showcasing his morning routine - brushing his teeth, signing his book and watching videos of his own show - has had more than 5m views.

In an 2019 interview, Judge Caprio said his courtroom proceedings "show a slice of life of Rhode Island that is very interesting, and it reflects the same issues people are experiencing nationwide".

David Caprio, his son, thanked fans for their love and support and urged people to "spread a little kindness" in his father's memory.

In an Instagram statement to his 3.4 million followers, Judge Caprio was remembered for the "countless acts of kindness he inspired".

"His warmth, humour, and kindness left an indelible mark on all who knew him," the statement said.

During its run, Caught in Providence was nominated for three Daytime Emmys, with Judge Caprio earning two of his own nominations last year.

The company behind it, Debmar-Mercury, paid tribute to Judge Caprio's "unique brand of compassion and common sense approach".

"We will miss him dearly," co-presidents Mort Marcus and Ira Bernstein said in a statement.

After being diagnosed with pancreatic cancer in 2023, Judge Caprio said he was "fully prepared to fight as hard I can" and thanked followers for their support.

In one of his last social media posts, Judge Caprio announced he was back in hospital after suffering a "setback" in his treatment and asked his followers for their prayers.

Judge Caprio is survived by his wife of nearly 60 years, Joyce Caprio, as well as their five children, seven grandchildren and two great-grandchildren.
