British police say disgraced former House of Lords member John Sewel will not face drug charges because of insufficient evidence against him.

Sewel resigned from the House of Lords in July after he was photographed cavorting with two prostitutes and allegedly snorting cocaine. Police launched an investigation and searched his apartment after the photographs were published by the Sun on Sunday newspaper.

A police statement Tuesday said the investigation has now been closed and no further action will be taken.

The married 69-year-old Sewel stepped down and apologized for the "pain and embarrassment" he caused. He was a deputy speaker of the House of Lords and chaired its Privileges and Conduct Committee before he stepped down.
