Police officers were given medical treatment at the scene as some 80 people were evacuated from their homes when “potentially hazardous material” was found in a flat.
Seven police officers and a Scottish Police Authority forensic service staff member took unwell and were treated on site in the east end of Glasgow.
A Royal Navy bomb disposal team was called to the incident on Monday night as police cordoned off several streets.
Police arrived at the flat on Altyre Street, Shettleston shortly after 5pm on Monday evening and remained onsite well on Tuesday.
Residents, whose homes were evacuated as a precaution were allowed to return home by Tuesday morning.
The affected streets – Alytre Street, Dalness Street, Ard Street and Trainard Avenue – were reopened, having been closed overnight.
Chief superintendent Alan Waddell said: “Our inquiries into the incident are ongoing, and there will be a continued police presence in the area. We are working closely with our partners.
“I would like to thank residents and motorists for their patience whilst we dealt with this incident. There was no danger to the wider public.”
