European Commission President Ursula von der Leyen says she is "deeply shocked" by the "brutal and insidious attack in Solingen".

In a social media post, she says: "My thoughts are with the families of the dead and the injured, to whom I wish a speedy recovery."

She thanks the police and rescue services, adding: "We need to quickly clarify the background to this crime."

We've just heard from German police and state prosecutors who gave an update on the current situation following the attack at the western German city of Solingen.

Here's what they said:

• Police revealed that a 15-year-old had been arrested in connection with the case
• The teenager is suspected of knowing about the attack beforehand and not reporting it to police
• Police added the identity of the attacker remains unclear and that investigations are ongoing

• They also confirmed that three people died - two men - age 67 and 56 - and a woman, 56
• Eight other people were injured, four are fighting for their lives, police said
• The suspect's motive is unknown but police said they cannot rule out a "terrorist motive"
• The chief of police urged people not to speculate on social media and appealed to the public for more information
• Police also revealed that they found "multiple knives" and were looking into whether one of them was involved in the attack
• The attacker appears to be unknown to the victims, they added

The press conference has now ended.

Police said a 15-year-old had been arrested in connection to the stabbings in Solingen.

He was detained this morning after two women reported overhearing a conversation between the 15-year-old and someone else in which they discussed the attack.

The teenager is suspected of knowing about the attack beforehand and not reporting it to police.

The identity of the attacker is still unclear.

While one person is in custody, investigators are still trying to establish exactly who carried out the attack.

Officials are now asked about the eight people who are injured.

One of the officers says there are four "very seriously injured" people in the hospital who are undergoing medical treatment.

"We hope that soon their lives won't be at risk," he says, adding that "things are moving in the right direction".

Another officer confirms that there are four people who are fighting for their lives.

Police say there was no specific terror threat before the festival and there was not a large security zone in place.

The situation on the ground after the attack was "very hectic", police say, which made it difficult to find a perpetrator.

Asked about reports that the attacker targeted victims' throats, police say yes, attacks were "very targeted" at people's throats and necks.

Caspers repeats that police are look at terror motive, adding that there's no other obvious motive and that the attacker appears to be completely unknown to all victims.

He also says people are "seriously injured" but does not provide further information on their conditions.

Due to the "brutality and complexity" of the attack, police say they have a lot of evidence to look at.

They have found "multiple knives" and are attempting to determine whether one of them was used in the attack.

They cannot currently confirm whether they do have the weapon that was used.

Now over to questions from journalists.

In answer to the first question, police chiefs say they are unable to say anything else about the investigation while it is ongoing.

Pressed again, the officer declines to give further information on the 15-year-old suspect and confirm that they are not releasing any images of the suspect.

He is then asked about online speculation there were two attackers.

He says is not aware of those reports and will not comment on the investigation. He says he's not aware of any witnesses talking about two attackers.

Police are continuing to search for an individual who was allegedly heard discussing the attack plan with the 15-year-old who is in custody.

The chief of police appeals to the public for more information and urges people not to speculate or share information on social media.

There will be an increased presence during the ongoing investigation, he says.

Police say that they don't yet know the suspect's motive, but that they cannot currently rule out a "terrorist" motive.

The chief of police on duty last night now says that everyone is thinking of those who have lost their lives and those who have suffered because of this "hideous attack".

He says they received multiple calls at around 21:40 local time last night about a male attacker who was attacking people at the festival.

The attack happened at Fronhof, he says.

A large number of police officers have been deployed, he says, adding the ongoing search action involves both local and federal police forces.

Police say they have arrested a 15-year-old in connection with the case.

Three people have died. Two men aged 67 and 56 and a woman aged 56.

Police Chief Markus Röhrl starts his opening remarks by saying yesterday's festival for the 650th anniversary of Solingen should have been a happy event, but instead became a "terribly sad one".

As a note, Solingen Mayor Tim Kurzbach was unable to attend the press conference.
