Security firm that employed Orlando killer sees stock slide

Shares in the security company G4S fall over 5 percent after it emerges that the killer in the Orlando nightclub attack worked for the firm.

The company’s shares fall 9.6 pence to 177.80 on the London stock exchange after the company acknowledges that Omar Mateen worked for G4S at a residential community in south Florida. The company says Mateen was subject to a detailed screening and checks by US law enforcement, which reported no findings to G4S.

G4S, a global security company, is active in some 100 countries and has 610,000 employees. It came under fire during the 2012 London Olympics after failing to provide the number of security guards promised to protect the games. The British military had to be called in to fill the gap.
