Cara Delevingne's house fire investigation meets dead end

Cara Delevingne's house fire case has been left hanging in the dry.

The Los Angeles Fire Department has ruled the official cause behind the massive blaze as “undetermined.”

According to TMZ, investigators have not been able to identify exactly how the 31-year-old model's $7M mansion caught fire.

The confirmation comes after Cara’s parents had speculated that the tragedy may have been sparked by an electrical issue.

However, the “extensive damage” made it difficult for the arson squad to determine the cause as they have now officially closed the case.

Besides this, the officials made it clear that there were no signs of foul play.

The update comes after Cara’s house in Studio City, California was engulfed by a massive fire on March 16, causing the roof to collapse.

According to information released by the LAFD at the time, it took 94 firefighters to put out the flames at the backside of her 6,650-square-foot home.

They had revealed that the blaze consumed one room in the back of the house and developed into "a deep-seated attic fire."
