A Metropolitan Police officer was stabbed in the face with a pen in a "vicious and unprovoked attack" while making an arrest in north London.
Police were called at 10.25am on Sunday to a report of a suspect in the garden of a property in Manor Park Crescent, Edgware.
When they arrived in the garden, one of the officers, a female Pc, was attacked with the pen.
She has been taken to hospital for treatment.
Her condition is not life-threatening but the extent of her injuries are unknown.
A 39-year-old man was Tasered by officers, before being arrested on suspicion of breach of bail, as well as offences against the officer including threats to kill and GBH.
He has been taken to hospital for treatment.
Roy Smith, BCU Commander for North West London, said: “Sadly this is yet another reminder of the risks faced by our police officers as they respond to calls for help from the communities of London.
“The men and women of the Met go to work each day not knowing the dangers they may face. They run towards danger to protect others and their everyday heroism is something all Londoners should be proud of."
He added: “This officer was subjected to a vicious and unprovoked attack. These are our police officers and they have family and loved ones to return home to. They deserve not only our admiration but also support.”
