Tributes have been paid to the woman who died when masonry fell on to her in Mayfair.

Amanda Telfer was pronounced dead at the scene after being struck by building debris, believed to be a concrete window frame, in Hanover Square, on Thursday.

She was a lawyer with Keystone Law, and also worked for the human rights group Reprieve.

A statement on Keystone Law’s website said: “Amanda Telfer, a consultant solicitor at Keystone Law, was killed in a tragic accident on London’s Hanover Square on 30 August 2012. We would like to pay tribute to Amanda who was an extremely talented lawyer, much admired by her clients and colleagues.

“Amanda joined Keystone in 2005 and specialised in libel, defamation and privacy law.

“She represented several high profile clients and worked for the human rights group, Reprieve. Amanda was always a pleasure to work with and we shall miss her greatly. Our thoughts are with Amanda’s family at this difficult time.”

The cause of death was blunt force trauma, a post-mortem carried out on Saturday found, and police are working alongside the Health and Executive Executive (HSE) to try to establish what happened.

An inquest is due to be opened and adjourned at Westminster Coroner’s Court tomorro at 9.30am.

No further details about Ms Tefler are being released by the Metropolitan Police, at the request of her family.

An air ambulance, two cycle responders, two ambulance crews and members of the hazardous area response team were sent to the scene and extensive efforts were made to resuscitate Ms Telfer following the incident.
