Warren Sapp was arrested in Phoenix this morning for soliciting a prostitute around 7AM ... TMZ Sports has learned.

Sapp was also arrested for assault. We're told Sapp was taken into custody at a hotel in Downtown Phoenix.

The 42-year-old "Dancing with the Stars" alum was booked just a few minutes ago.

Sapp was in Phoenix covering the Super Bowl for the NFL Network.

It's not Warren's first arrest -- he was busted in 2010 for domestic battery, but those charges were eventually dropped. He was also arrested for an alleged domestic battery in Miami in 2014.

As we previously reported, officials made it clear before the Super Bowl they would be cracking down on prostitution.
