A convicted fraudster housed in a maximum security prison in Nigeria managed to pull off a $1m (£775,000) online scam from behind bars.

The African nation's Economic and Financial Crimes Commission this week said Hope Olusegun Aroke, who is serving a 24-year stretch for a previous fraud conviction in 2015, used a contraband cellphone and a network of accomplices outside prison to scam foreigners out of money online.
