Today’s arrest of former X Factor judge Tulisa Contostavlos comes after the Metropolitan Police said its officers were "considering" information following an article in the Sun on Sunday.
The newspaper suggested Contostavlos had acted as a go-between in a drug deal by introducing a journalist to an alleged supplier.
The report suggested half an ounce of cocaine changed hands as a result of the deal conducted at London's Dorchester Hotel.
Former X Factor judge Tulisa Contostavlos arrived home in Hertfordshire today following her arrest on suspicion of supplying class A drugs.
The 24-year-old singer first found fame with N-Dubz and was dropped as a judge on The X Factor last month.
