Several days of rioting and looting in London have turned into a temporary boon for the sporting goods business.
Figures from Amazon.co.uk show that sales of self-defense items like bats have skyrocketed in recent days.
Paywell's Military Police Telescopic Tonfa also saw a rise of more than 5,000 percent.
Some wooden bats were up as much as 3,664 percent.
Other items like tents and headband lamps also benefited during the period of unrest.
Londoners began cleaning up their city after a third night of riots on Tuesday, aided by a Twitter and Facebook campaign which rallied people to the most damaged areas.
Fires broke out across the capital on Monday night as looters smashed up and set ablaze buildings, shops and cars, while violence also broke out in the cities of Birmingham, Liverpool and Bristol.
Prime Minister David Cameron recalled parliament Tuesday and promised to crack down on protesters if the riots continued.
"You will feel the full force of the law, he said. "And if you are old enough to commit these crimes, you are old enough to face the punishments."
Update (1:40 p.m. ET): Amazon.co.uk now lists sales for the Rucanor Aluminium Baseball Bat as being up 6,541 percent.
