Geoff Pooley, 31, and four pals went to see Blaine in his perspex box at 2am armed with lemons, nectarines and peaches.

But the property boss says that before he threw anything, he was punched in the head and hurled against a fence by guards.

He was knocked unconscious and suffered a gash above his eye.

Geoff, of West London, said: “We were only having a bit of fun but the security men were just out of control.”

He was taken to hospital where his wound was stitched. But last night the security men claimed THEY were attacked first.

A spokesman said: “Two individuals had been throwing missiles at the box. When the guards tried to remove bags of fruit from one of them he refused and the individual threw a punch. The guard reacted with one single defensive blow.”

Under attack ... a weary and dishevelled David Blaine yesterday

Dishevelled David, 30, was yesterday heading for his 13th night in the box near London’s Tower Bridge — with his 44-day challenge due to end on October 19.

Meanwhile, the man held after scaling scaffolding to rock the box said he did it as a protest.

Stephen Field, 38, of Godalming, Surrey, said: “There are starving people in the world and Blaine does a stunt like this — it’s sick.”

Gays launch sausage blitz

HUNDREDS of gays are to attack Blaine’s box with raw sausages in a bizarre internet stunt.

An email sent to thousands of users by gay site outintheuk.com calls on them to meet at a bar in Soho on Saturday, before descending on Tower Bridge.

The message reads: “Everyone bring five sausages and a throwing device. The person who gets the closest to hitting David Blaine with a sausage wins.”

They are being urged to bring chipolatas — because they are more aerodynamic.
