The force also said that laser pointers, drones, fireworks and flares are also prohibited.
The Asia Cup starts on Saturday at Dubai International Stadium. Dubai Police posted the reminder on social media.
It also stated that sharp objects, scooters, outside food and drink and filming are banned.
The 16-day tournament was supposed to be held in Sri Lanka but the political situation in the country meant it was moved to the UAE.
Dubai is hosting the majority of the matches at this year’s tournament, including the highly anticipated clash between India and Pakistan on August 28.
The emirate also hosts the final on September 11, with the rest of the fixtures taking place in Sharjah.
“We are delighted to host the 2022 Asia Cup, the second largest cricket event in the world,” said Khalid Al Zarooni, chairman of the board of Dubai Sports City.
“It is watched by millions of fans across Asia and beyond. Dubai International Stadium will host the tournament for the second consecutive time. The last edition was also held in Dubai in 2018," Mr Al Zarooni said.
“This reflects Dubai’s status as the best city to host such mega-events.”
