(BBC) A man tried to buy grenades and Semtex explosive from an undercover FBI agent on the dark web, a court has heard.
Mohammed Humza, 29, of Watford, is accused of contacting the agent, who was posing as a seller on trading site AlphaBay, in 2016.
The Old Bailey was told a Tor browser, designed to hide the location of the user, was found on Mr Humza’s laptop.
He denies the charge and says he was not in control of the mh.nn243 username linked to the purchase.
Prosecutors said part of the defendant’s email address was similar to the dark web ID, which included the initials mh and nn.
