The order has been put in place after the incident which resulted in a 17-year-old boy sustaining injuries after being stabbed at around 3.30pm.
The Section 60 order applies to the areas shown on the map pictured, including the Langley area of Slough.
This order is in place from 6.20pm today (21/10) and will last until 10am tomorrow (22/10) whereupon it will be reviewed and, if deemed necessary, extended for a further period.
Inspector Craig Woolnough, based at Slough police station, said: “I fully appreciate the concern that incidents such as this cause in the community, and that has led to this Section 60 order.
“Whilst this order is in place, there will be an increased presence of uniformed police officers in these areas. They will be providing reassurance and are also there to prevent any reoccurrence of any such incidents from taking place.
“Under the order, our officers have been given authority to use their powers under Section 60 with effect from 6.20pm today.
“These orders exist to help the police prevent serious violence and we do not take decisions to enact them lightly.
“Please do not be worried if you are stopped by an officer as this does not mean that you are in trouble, this is just one method that we are using to ensure weapons are kept off our streets.
“You will see an increased police presence in these areas whilst the order is in place and we do expect to carry out more stop and searches than usual.
