Manchester City striker Mario Balotelli escaped unhurt when a firework was launched inside his home.
Firefighters were called to the Italian's detached Cheshire house when the explosive set alight his bathroom in the early hours of Saturday morning.
Police said it was an accident and have decided not to take any action.
The incident happened less than 48 hours before leaders City travel to neighbours Manchester United in a table-topping Premier League clash.
Officers confirmed Balotelli, 21, was inside the property in Mottram St Andrew but it is believed he did not set off the firework.

PC Shelley Williams, from Cheshire Police,
told the Manchester Evening News newspaper
: "At just before 1am on the morning of Saturday 22 October, Cheshire Police were called to a report of a house fire at a residential home on Oak Road, Mottram St Andrew near Macclesfield.
"Police provided assistance to Cheshire Fire and Rescue Service in ensuring residents were accounted for and there was no danger to surrounding properties.
"At this time the cause of the fire is being examined by fire investigators and police. However, it is not thought to be suspicious."
Four firefighters arrived wearing breathing apparatus and used two hose reel water jets to douse the flames and a large fan was also used to clear smoke from the house.
Balotelli has been involved in a number of controversial incidents since
joining City in a reported £24m move from Inter Milan in August 2010
He was sent off against Premier League rivals West Brom in November before his manager Roberto Mancini labelled him "stupid" for seeing red again in a Europa League game against Dynamo Kiev.
Only last week he was embroiled in a spat with Aston Villa fans
after netting in City 's 4-1 win
against their side.
And City officials launched an investigation in March after the Italy international threw a dart towards a youth team player at the club's Carrington training ground.
