London-listed ARMS, previously known as Bumi, has breached various rules applicable to listed companies, the FCA said in a statement.

ARMS, with coal assets in Indonesia, has been hit by tumbling coal prices, a series of boardroom disputes and allegations of fraud and corruption.

The company, which was recently at the centre of a control battle, has seen its shares lose about 90 percent of their value since its 2010 listing.
