Are you referring to the patrol bomb attack on a police car in Northern Ireland?
Oops, no, you weren't, since you explicitly wrote England.
May I ask to what incident you are referring?
(In England and Wales you can't legally create bombs to kill someone, be it a fellow citizen or anyone else. The relevant laws are: section 4 of the Explosive Substances Act 1883, Offences against the Person Act 1861, Criminal Damage Act 1971, Health and Safety Act 1974, and Fireworks Act 28003. And probably the Terrorism Act 2000 and Terrorism Act 2006, too.])
