On May 24, the UK Financial Services Authority (FSA) announced that it had fined Samuel Kahn £1,094,900 (approximately $1,790,000) and obtained a High Court injunction restraining him from committing market abuse. This was the first time the FSA had secured such a final injunction from the High Court.

The FSA stated that in March and April 2010, Mr. Kahn carried out a scheme to deliberately inflate the share price of Global Brands Licensing plc (GBL), a company quoted on PLUS Stock Exchange, a UK Recognized Investment Exchange. In that period he controlled the vast majority of the trading in GBL's shares and disguised this by impersonating others when placing orders. Mr. Kahn's false trading moved GBL's share price from 2 pence to 5.25 pence.
