Pictured: Female police officer killed in second Paris shooting was '27-year-old rookie who dreamed of serving her country'

A French police officer shot and killed in the second horrifying gun attack on Paris's streets in less than 24 hours has been named as a 27-year-old rookie who 'dreamed of serving her country'. 

The young policewoman who was gunned down as she attended a routine traffic accident in Montrouge at 8am today is called Clarissa Jean-Philippe, according to the French media.

She was unarmed and had only been in the job for 15 days. Police arrested two men over the killing tonight.

A second victim - a street cleaner who was shot in the face after he confronted the gunman - is said to be in a serious condition.

This shooting came less than 24 hours after the massacre at the Paris offices of Charlie Hebdo, which left 12 dead - including two police officers. It is not known if the two attacks are linked.

Meanwhile, terrified workers in Paris’s business district La Defense were warned not to leave their office after a gunman was seen outside, French newspaper Le Figaro reported.
