Three women have been hurt by falling into Tate Modern's latest installation - a crack in the floor. One observer said: "Instead of art imitating life, here it's threatening life."
One onlooker said: "We saw the first victim, a young woman who went into it with both feet up to just below her knees. She had to be dragged out by her friends.
"As we watched to see whether she was okay, an older woman deliberately stepped on it, lurched forward and landed on the ground. She told us she thought the crack was painted on the floor."
They were attended to immediately by Tate security staff trained in first aid but there have been no serious injuries.
