Police confirmed on Monday security was increased around the England and Australia dressing rooms on the final day of the third Ashes Test in Birmingham at Edgbaston.
Extra stewards were drafted in to the pavilion area at lunch following a tip-off but security was back at standard levels during the first hour of the afternoon session.
A West Midlands Police spokesman said: "We can confirm there was a short security alert at Edgbaston this (Monday) afternoon.
"Officers at the scene investigated and found this to be nothing of concern. The incident has now been declared safe."
