Boxer JoJo Diaz Arrested For Child Neglect

Pro boxer Joseph “JoJo” Diaz — a former champ who fought Devin Haney back in 2021 — was arrested in the Los Angeles area on Monday … TMZ Sports has learned.

Jail records show Diaz was taken into custody by the Claremont Police Dept. just before 7 PM. Law enforcement sources tell us he was booked on a charge of misdemeanor child neglect.

The specific allegations against Diaz are still not clear … but records show he was released on Tuesday afternoon.

The 30-year-old fighter holds a 32-3-1 pro record. He famously won the IBF super featherweight title back in 2020.

Diaz went on to fight Haney in 2021 — but lost. Earlier that year, he was in talks for a match with Ryan Garcia, but they ultimately fell through.
