Additional specialist search and rescue units were then dispatched, including a search and rescue dog, according to the spokeswoman.
“We’ve got no indication of what the cause is at this moment,” the spokeswoman said.
Four people have been taken to hospital following the incident, the ambulance service said.
City hospital the Leicester Royal Infirmary said it was treating the four patients, who were “in a critical condition”.
It advised people to only attend its accident and emergency department “if absolutely necessary”.

Graeme Hudson told AFP he lives close to the scene and felt the blast.
“It was very scary,” he said. “I live five minutes (away)... but my house shook. I went out and saw massive smoke and big flames.
“I quickly went out to see what’s happened,” he added. “(I) didn’t stay for long there because (I felt) unsafe for my 11-year-old son.”
Sources told Britain’s Sky News that initial investigations indicated there was no connection to terrorism.
