France: calls grow for answers over police killer’s radicalisation

Pressure on ministers to explain how warnings were missed before deadly attack

Pressure is growing on France's government to explain how the radicalisation of a man who killed four colleagues at the Paris police headquarters failed to raise red flags inside the intelligence unit where he worked.

The interior minister, Christophe Castaner, summoned before two parliamentary committees this week, conceded there had been a "malfunction" as he promised to "tighten the net".
