London-based private equity company Charterhouse Capital Partners was said to be thinking of offering GBP 1 billion for the cash solutions unit of G4S. Three sources told Bloomberg that Charterhouse proposed to finance a deal with G4S and that the latter was said to be discussing the offer internally. No formal discussions have been made yet, according to the people.

However, one source said G4S may not sell its cash solutions business. 

Based in Crawley, England, G4S is a security services provider. It specializes in providing high-security vehicles to transport cash. It also manages ATM machines. 

In August, G4S Chief Executive Officer Ashley Almanza said the company would be divesting its Canada-based cash solutions unit as well as its Columbia-based data business. One of the sources also revealed that other private equity companies were interested to acquire the Canada business. In a report published late last month, the Sunday times said some investors of G4S, like hedge fund Cevian Capital, was pressuring the company to sell both units.
