KARL Robinson was unhappy as Oxford United's season ended amid a pitch invasion at Luton Town.

Some Hatters fans ran on at the final whistle to celebrate the Sky Bet League One title, which was secured with a 3-1 victory against the U's.

It saw the visiting players scatter, some heading to the travelling fans and others heading for the safety of the tunnel.

The Town supporters ended up congregating in front of the 1,025 fans, where stewards and police held them back.

But it did not stop objects being thrown into the away section, including a smoke canister, before the crowd were finally dispersed.

Robinson said: "The safety of players is of the utmost importance.

"There were canisters thrown above our heads and back again.

"Two got through into our fans, one came out and our fan got chucked out. But the police didn’t do anything.

"It’s rubbish because Mick (Harford) has done incredible here and the players are deserved champions and I don’t want it to tarnish what has been a great year for them."
