Firefighters responded to a small fire in a stairwell in Providence Place this evening.
Nobody was injured and the cause is being investigated, according to Station Manager Michael Humphreys, who was on the scene.
Firefighters cordoned off the plaza and the large Sainsbury's store had to be evacuated.
Several crews, including ones from Maidenhead and Langley, were in attendance, and at least three engines were present.
Station Manager Humphreys said that was because the incident was close to flats.
At 8.42pm, Thames Valley Police Maidenhead's Twitter account posted: "We're investigating a fire at Providence Pl, Maidenhead earlier. Fire out. Good news is nobody injured. Some rd closures in place nearby."
Earlier, a police officer at the scene told the Advertiser they were responding to an 'incident' but was unsure what the cause was.
Speaking at about 8pm, he said there was still some smoke for the firefighters to take care of.
By 8.20pm, firefighters were packing up and removing cordon tape at the plaza.
At 8.35pm, a shutter at the entrance to the Sainsbury's at the north end, by St Cloud Way, was still shut but staff could be seen inside.
UPDATE Tuesday, July 4, 9.05am:
Police say they are treating last night's fire as arson.
In an update on the Thames Valley Police Facebook page, the force said emergency services were called to a fire in a block of flats in Providence Place at about 7pm and it was 'fortunate nobody was injured'.
Speaking this morning, Watch Manager Hayden Jenkins, at Maidenhead Station, said: “There was a relatively small fire on the ground floor of the fire escape in Providence Place.
“However, the contents of the fire produced thick black smoke which caused smoke logging in the first floor corridor.
“We sent six appliances, which is the normal procedure for high rise buildings. Firefighters used a dry riser to tackle the incident.
“We asked that all the residents used the Stay Put policy.”
A Sainsbury’s spokesman said: “Customer and colleague safety is our top priority. The store was closed as a precautionary measure due to a fire on nearby land. The store is now open as usual.”
Call police on 101 quoting reference 1438 3/7 with any information.
