The Isis-inspired attacker who stabbed to death a French police commander outside his home had compiled a number of targets including "rappers, journalists, police and public figures".

Police found the list of six names on Larossi Abballa's personal computer, prosecutor Francois Molins revealed.

The targets were found after police stormed the victims' home in Manganville, a suburb 35 miles west of Paris.

Abballa reportedly shouted "Allahu Akbar" as he stabbed a policeman nine times in the stomach before holding the officer's wife and three-year-old son hostage in their home.

After negotiations failed, an armed RAID unit stormed the house and shot him dead. The chief's wife was found dead but their child was rescued unharmed.

It has also emerged the killer broadcast the attack live on Facebook, a source close to the anti-terrorism investigation revealed.

During the live broadcast, Abballa was allegedly shown to consider what to do about the couple's son, according to French jihad expert David Thomson.

The 25-year-old attacker was being monitored by security and anti-terrorist services after he received a three-year prison sentence in 2013 for recruiting Islamist militants to go to Pakistan.

Three other people linked to Abballa have been arrested and placed into custody, Prosecutor Molins said.

The attack has been claimed by Isis, according to the website of the Amaq agency. French authorities have said they have "no reason" to doubt the claim.

If the link is confirmed, it would be the first militant strike on French soil since the government imposed a state of emergency after the Paris attacks in November that killed 130 people.

French newspaper, Le Parisien, has reported the 42-year-old police commander was Jean-Baptiste S, deputy chief of judicial police at the nearby Les Mureaux police station.

It has also been reported he previously worked at a station in Mantes-la-Jolie where Abballa lived.

President Hollande described the murder of policeman and his 36-year-old wife Jessica S. as "unquestionably a terrorist act", adding that France was facing "a very significant threat".

On a Facebook account said to belong to the attacker, a post announces his "success" in killing a police officer and his wife at their home, claiming that "the brothers in Sham [Isis territories]" are in contact with him.

The post continues: "I declare loudly and strongly my allegiance to the Emir Abu Bakr al-Baghdadi.

"I have responded to the call of Sheikh Abu Muhammad al-Adnani."

Isis spokesperson Abu Muhammad al-Adani has called for a series of lone wolf attacks during the Islamic holy month of Ramadan.

Acknowledging possible defeat in the group’s strongholds of Mosul, in Iraq, Sirte, in Libya and Raqqa, in Syria, he urged followers to create a “month of calamity for infidels”.
