A Los Angeles homeowner was left horrified after he saw a man fiddling with a tree outside of his Hollywood mansion, before the suspected arsonist started a fire.

The LA Fires have been razing neighborhoods to the ground as 40,600 acres have become scorched in the past two week - but it seems one man was caught on camera attempting to ignite another blaze in Hollywood.

Mission: Impossible actor, Ricco Ross, woke up on Monday to reports that someone had tried to start a fire with a palm tree in his neighborhood on Fuller Street around 6:30am.

'Woke up this morning and heard that two doors down, somebody had set fire to a tree to try and start a whole fire in West Hollywood,' he said as he walked around his Melrose neighborhood.
