At least six people were injured Thursday morning when a double-decker bus crashed into a shop on a busy London street, CNN reported.

Police said the driver was taken to a hospital; emergency services freed two passengers trapped on the top deck using an aerial ladder.

Andrew Matthews, who said he was on the bus when it crashed shortly before 7 a.m., told the UK Press Association he heard yelling and screaming.

"I noticed the bus drifting. I heard a smash and saw the roof of the shop going through (the bus) from the front left. It went to the fourth or fifth row," Matthews said.
