ARSENAL fans were left fuming after their Europa League exit - with the Emirates Stadium briefly placed on lockdown.
Trailing 2-1 from the first-leg in Spain, the Gunners failed to find that all-important goal at home to Villarreal as they drew 0-0 to crash out of Europe.
Not only did Arsenal miss out on the chance to take on Manchester United in the final in Gdansk later this month, they also lost their best shot of qualifying for any continental competition next season.
Currently ninth in the Premier League, the Europa League KO only served to pile more pressure on Mikel Arteta with former boss Unai Emery coming back to haunt the Gunners.
And eyewitnesses claim the Emirates was briefly put on lockdown after the game as officials feared protests getting out of hand.
Crook tweeted: "We have been locked in the car park compound as a handful of angry #AFC fans have stormed the entrance.
"Saw fans screaming through the railings at the team coach as I left as well."
Arsenal fans had continued their protests against current owner Stan Kroenke and his company KSE over their involvement in the failed European Super League plot before kick-off.
Two weeks ago - ahead of the 1-0 defeat at home to Everton - some supporters even hung an effigy of the American billionaire, with police forced to intervene.
Other clubs around the country have also been protesting, with Man Utd vs Liverpool even postponed after fans broke into Old Trafford.
