British police investigating the murder of 16-year-old Mary-Ann Leneghan said tonight that two fresh arrests had been made.
A 21-year-old man was arrested in Paddington, west London tonight, following the arrest of an 18-year-old in Battersea, south London, earlier.
The latest developments take the total number of people who have been questioned over the 16-year-old's murder earlier this month to 15.
Four men from the London area have already been charged with the abduction and murder, and with the attempted murder of Mary-Ann's friend.
