Vince Neil -- Booted Fan Came Back for More Punishment

Motley Crue singer Vince Neil nearly paid a dear price for attempting to punch a fan in the front row at a concert last weekend ... because after the fan got booted, the man came back to settle the score ... with an entourage of goons.

A rep for Inn of the Mountain Gods casino in New Mexico -- where the concert took place -- tells TMZ, "During the post-performance party at the property, the intoxicated fan and his group of friends, who were also visibly inebriated, returned and continually attempted to get close to Vince."

The rep says the group followed Vince to the private section where he was chilling with the band.

Thankfully, we're told the group -- hell-bent on revenge -- was intercepted by security ... and the fan was subsequently escorted from the property.
