Two Scandinavian tourists killed in Morocco were slaughtered by a 'lone wolf, hastily organised terrorist cell' who travelled to the village of Imlil knowing it was popular with foreign hikers.

Moroccan police yesterday arrested five more people for the murders of Louisa Vesterager Jespersen, 24, from Denmark, and Maren Ueland, 28, of Norway, bringing the total in custody to 19.

At a press conference in the country's capital, Rabat, domestic intelligence spokesman Boubker Sabik labelled the suspects 'lone wolves'.

The news follows a candle-lit vigil in memory of Louisa and Maren at the Town Hall Square in Copenhagen yesterday and one in Rabat, Morocco earlier this week.

Sabik added that 'the crime was not co-ordinated with Islamic State'.

The revelation is in contrast to the killers pledging allegiance to Isis after stabbing their victims multiple times and filming a beheading of one of the women.

There were four main suspects all arrested within days of the murder.

It has also emerged that the two women were 'happy and sociable' in their final days, according to Rachid Imerhade, a mountain guide who had met the two friends a few days before their deaths.

He said: 'They were smiling, chatty and sociable. They talked a lot with the other people around.'

Jespersen's mother, Helle Petersen, told the Danish newspaper B.T. that her daughter was 'always happy and positive. Everyone loved her and she saw the best in everyone'.

They recruited up to fifteen others and pledged allegiance to Islamic State, but authorities said this was without any prior agreement with the terrorist organisation.

'The emir of the group' - noble military leader - was Abdessamad Ejjoud, a 25-year-old street vendor living near Marrakech, the others were acting on his command, according to Sabik.

Ejjoud had 'formed a kind of cell that discussed how to carry out a terrorist act inside the kingdom,' he told AFP.

Investigators claim that Ejjoud is one of the men pledging allegiance to ISIS in a video shared a week before the brutal killings.

Two prior the murders, the killers travelled to the mountainous Imlil region 'because it is frequented by foreigners' and 'targeted the two tourists in a deserted area', Sabik added.

Other men suspected of direct involvement included a plumber, a carpenter and a second street vendor.

Sabik said none of these men had contact with 'IS operatives'.

The men were all arrested during police raids that also uncovered weapons and bomb making materials.

Investigators said on Monday that the dismantled 'cell' was made up of 19 members, including three with terror-related criminal records.
