German investigators are still searching the ruins of the building which went up in flames on Sunday killing nine people, including five children.

According to police, the Neo-Nazi graffiti that were found on the charred wall of the building in the city of Ludwigshafen didn’t have any connection with the fire.

The four-story apartment from Ludwigshafen was home to some Turkish families and the nine victims were all Turkish citizens or Germans of Turkish descent.

On the wall next to the entrance to a ground-floor Turkish cultural center in the building the German word “hass,” meaning “hate”, was written. The letters “ss” were written in the Nazi “SS” rune script, reminding of the racists attacks which occurred in Germany in the 1990s.  

However police determined that the graffiti were there before the Sunday fire thus showing that the two were not related.

Spokesman Volker Klein said: "At this point, we don't see any connection with it and the fire," the Associated Press reports.

The investigators were able to search the building on Wednesday after it was secured. They’ve searched the ruins with the help of dogs trying to find clues that could lead them to the cause of the fire.

The building suffered a similar attack two years ago in August 2006 when two petrol bombs were thrown at it, but the fire was controlled by residents.

Police is now working with the information they’ve received from two girls of 8 and 9, who said that they saw a man who set something on fire and then threw it into a baby carriage placed in the hallway of the building.

The fire was blamed by Turkey's Prime Minister Recep Tayyip Erdogan and was wondering is racisms was the cause of the fire.

Erdogan said that four policemen and a government official will come to Germany to start an investigation of their own.

The site of the accident was visited by Turkey's ambassador, while Erdogan is expected to do it later Thursday. He will also meet with the survivors.
