Retired American footballer Keyshawn Johnson has been arrested on suspicion of domestic violence.

Justin Bieber's former neighbour was taken into custody on Monday morning (21Apr14) following an alleged bust-up with his ex-girlfriend at his Calabasas, California home.

He was booked for misdemeanour domestic battery and was released on $20,000 (£12,500) bail, according to

Johnson, who now works as a Tv pundit for U.S. sports network Espn, hit headlines last year (13) after fuming about Bieber's sports car-driving, fast-paced partying lifestyle in the gated community they shared in Calabasas.

They have both since moved out - Johnson sold his pad to Kourtney Kardashian in August (13), while Bieber offloaded his mansion to the reality Tv star's sister Khloe last month (Mar14).
