LONDON -- A woman was injured on Wednesday in an explosion at the vehicle licensing agency, the third attack in three days on motoring-related organizations.

BBC News said a parcel bomb had exploded at the Driver and Vehicle Licensing Agency (DVLA) in Swansea, south Wales. Police declined to comment on the nature of the explosion.

"One female has been taken to hospital with injuries which are not believed to be life-threatening," a police statement said. "The scene where the explosion took place has been cordoned off and evacuated."

The DVLA, a government agency that issues driving licences and keeps records of vehicles and motorists, said the injured woman handled its mail.

Susan Bailey, a spokeswoman for Swansea's Morriston Hospital, said the woman was in stable condition.

She said an unknown number of other casualties were being assessed at the scene by ambulance staff. The BBC said two people had been treated for shock.
The explosion followed letter bomb blasts on Monday and Tuesday at businesses linked to motoring payments or fines, raising speculation a motorist angered by the spread of traffic speeding cameras could be behind the attacks.

"Naturally these incidents are worrying. It is important that we allow police to get on with their investigation without undue speculation," Home Secretary John Reid said in a statement.


A letter bomb exploded at a business centre in Berkshire on Tuesday at the office of Vantis, a business services firm, injuring two men.

Newspapers reported the letter was addressed to "Speed Check Services" which supplies speed cameras to the police, but was sent instead to its accountants.

On Monday, a woman was injured in a letter bomb explosion at the London headquarters of Capita, the firm managing London's congestion charge. The company collects 25 million payments a year from motorists who pay to drive into central London.

Safe Speed, a pressure group which campaigns against the widespread use of speed cameras, condemned the attacks.

"While we don't agree with current road safety policy, that's no excuse for sending letter bombs. It's a behaviour we would roundly condemn," the group's founder Paul Smith said.

Motorists caught speeding by cameras paid more than 100 million pounds in fines in 2005.

"There is a groundswell of anger that we are subjected to a (motoring) policy that is onerous, unpleasant and ineffective," Mr. Smith said.
