Mardi Gra bomber confesses
Eltham High Street, London, after an attack on Sainsbury's
A 61-year-old man has admitted to being the Mardi Gra bomber who attempted blackmail against Barclays Bank and Sainsbury's supermarkets.
He will be sentenced at a later date.
His brother Ronald, 67, was jailed for a year after he admitted possessing a stun gun. Both men are from Chiswick, west London.
There were more than 33 incidents in and around London since the Mardi Gra bomber first struck in December 1994.
In the first attack, bombs were sent to six London branches of Barclays Bank in video cassette boxes. Three people were injured when some of the devices exploded.
In November 1997, small explosive devices blew up outside two branches of Sainsbury in west London and police defused another device outside a third store of the same chain in the same area.
In July 1997, police revealed that an extortionist had written to Sainsbury plc threatening to bomb the company's stores unless it paid "a considerable amount of money".
Pearce was arrested with his brother after they visited a bank machine, in a surveillance operation involving 1,000 police officers.
In court on Wednesday, Pearce, wearing a beige and cream knitted jumper and tinted glasses, stood with his hands crossed as he pleaded guilty to each charge.
His brother, who had been sitting next to him in a grey sweatshirt and jogging trousers, was led from the dock after he was sentenced.
