Sessions on dark web Alphabay and Hansa shut down

US Attorney General Jeff Sessions has announced the shut down of dark web marketplaces Alphabay and Hansa.

He also cautioned criminals from thinking that they could evade prosecution by using the dark web: "You cannot hide... we will find you."

The AlphaBay and Hansa sites had been associated with the trade in illicit items such as drugs, weapons, malware and stolen data.
