A woman is being treated in hospital after a letter bomb sent to the London HQ of congestion charge firm Capita exploded in her hands.
The female employee at the office in Victoria Street was injured when the bomb exploded.
It had been stuffed in a jiffy bag and detonated as she opened it in the sixth-floor postroom.
A Capita employee, who did not want to be named, said the woman normally opened the company's mail.
She said: "It can't have been addressed to her because she is the person who opens all the post.
"She is fine now but at the time she was very, very shocked. She had cuts to her hands and to her stomach, although it didn't go into her stomach.
"We don't think it can be terrorism as why would they target somewhere like our building?
"Maybe it is just somebody disgruntled with Capita."
After the explosion police immediately sealed off Victoria Street from Westminster Abbey to just beyond Scotland Yard.
An inner cordon prevented members of the public from accessing the building and all six floors of the office were evacuated. Employees later returned to work.
The MPS Counter Terrorism Command is investigating the explosion, which happened about 9.40am.
It is understood the bomb had apparently been addressed to someone specific in the company. Police have not identified the target.
