A Justin Bieber fan was left with a split lip after the singer allegedly punched him through an open car window in Barcelona.

TMZ has released video footage of the incident which shows the Spaniard run alongside the side of Justin’s car before receiving what looks like a punch in the face.

After the incident the fan explained that he was trying to touch the singer but wasn’t expecting Justin to retaliate with a punch to his face.

The group of fans all seem to be shocked by the incident as the teenager spits out blood and covers the wound with his hand.

The singer is currently touring Europe as part of his ‘Purpose’ world tour.
