Barcelona, May 16 (AP): The Spanish league is working with Espanyol to identify those involved in the field invasion that forced Barcelona players to cut short their title celebrations and rush into the locker room. The league said on Monday it was taking action a day after a large group of Espanyol supporters from the ultra section behind one of the goals jumped onto the field following Barcelona's 4-2 win and headed for the players who were singing and celebrating the Spanish league title. Espanyol Fans Storm Into Pitch, Chase Barcelona Players Amid La Liga Title Celebrations (Watch Video).

The league and Espanyol were analyzing television images to try to identify the fans and report them to authorities.

Riot police had to stand in front of the player tunnel entrance with shields to prevent the hundreds of fans from going in. Some Barcelona players exchanged words with the fans from inside the tunnel.

The Espanyol supporters threw chairs and other objects before dispersing without any other incidents. Barcelona Men's and Women's Team Players Celebrate La Liga, Liga F Titles With Fans in Victory Parade (Watch Videos).
