Police have named the woman who was killed when two buses collided outside Victoria station in central London.
Melissa Burr, 32, from Rainham in Kent, was pronounced dead at the scene of the crash at around 9am on Tuesday.
In a tribute, her family described her as a “kind and thoughtful soul” who had a “quirky charm”.
Witnesses said Ms Burr became trapped under one of the buses, which were both single-deckers on route 507.
Emergency services rushed to the scene but despite their efforts Ms Burr was pronounced dead.
Two other people were treated for non-life threatening injuries, police said.
No arrests have been made, the force added.
A spokesperson for Ms Burr’s family said: “We are absolutely devastated by loss and the hole that this incident has left in our lives.
“Melissa was a kind and thoughtful soul, had a quirky charm with such a bright future ahead of her.
“As a family we naturally want to understand how such a tragedy occurred, but for now we just want time and space to mourn our beautiful Melissa and send her to rest with her late father.”
