UK-based trader Saurabh Mehrotra has pledged to pay back $6m following a crude oil deal that ended up in London arbitration.

The son of London shipowner Ravi Mehrotra, he was the subject of a UK High Court order in June to repay the money, for which he acted as guarantor.

Mehrotra is being pursued by Hong Kong's Heritage Lane Oil & Gas Development and United Arab Emirates-based financier PTPY.
