A man suspected of decapitating a four-year-old girl was beaten by an angry mob as he was detained in Taiwan, with parliament saying it would debate tougher sentences for child-killers following the shocking crime.
The killer grabbed the child from behind as she cycled to a metro station in Taipei with her mother to meet relatives on Monday, police said.
Pushing away the mother of the girl, who had rushed forward to save her daughter, he beheaded the child with a kitchen knife.
Seven bystanders were unable to stop the man, who was arrested at the scene, police added.
The girl has been identified only by the surname Liu.
Police said the suspect, a 33-year-old man surnamed Wang, had been arrested in the past over drug-related crimes.
Taiwan's Apple Daily reported that he was unemployed and living with his parents, and had previously been hospitalized with mental health issues.
The case, the second child killing in Taipei in less than a year, has sparked widespread public anger and criticism of calls to abolish the death penalty.
Following the attack, parliament announced Tuesday it would bring forward a review of a bill that would ensure those convicted of killing children under 12 were given the death penalty, and at minimum a life sentence in the case of severe mental illness.
The review will now take place on Thursday, according to lawmaker Wang Yu-min, who proposed the bill.
"I am deeply saddened by the case ... (the suspect) should be sentenced to death in the case of a stranger killing a child," Wang said in a statement posted on Facebook.

The White Rose Social Care Association is planning to hold a mass rally in Taipei on April 9 to push for enforcement of capital punishment in the wake of the crime.
"This kind of random killing shows that Taiwan cannot afford to abolish the death penalty," said Eva Liang, chairwoman of the association.
"Since Taiwan seldom enforces death sentences now, the criminals are not afraid and similar crimes keep happening."
Television footage on Monday showed dozens of angry people gathering outside a police station in Taipei.
Some attacked the suspect as he was being transferred to the prosecutor's office for questioning. He pleaded with them to "stop beating".
Others came to lay flowers and toys at the spot where the girl was killed, near an elementary school, while a children's welfare group urged the public to join a rally next month in memory of the child.
A district court ruled that Wang was a flight risk and ordered him to be detained.
