An illegal immigrant hooked on drink and drugs is the chief suspect in the killing of an Amsterdam creche owner earlier this month, police said on Monday evening.

Arzu Cakmakci-Erbas was stabbed to death in a car park after locking up the Moeders Schoot childcare centre in the Geuzeveld district of the city on August 11 in what police said appeared to be a random attack.
On Monday, police circulated photos of Nevzat Koyak, aged 41, who they believe carried out the attack. A reward of €5,000 has been offered for information leading to his arrest.
