Fire crews in the city and county were called to deal with incidents within an hour of the start of the latest firefighters' strike tonight.
A single crew and a small fires unit were called to a road collision involving two cars in Burleys Way, near St Margaret's bus station in the city centre at 6.55pm - less than an hour after the four-hour strike began at 6pm.
Two casualties had already been helped from the vehicles by police and ambulance crews and one casualty was taken to Leicester Royal Infirmary.
At 7.15pm a fire crew responded to an automatic fire alarm which went off at Waitrose supermarket in John's Court, Blaby, after a strong smell of smoke was reported.
Firefighters, using a thermal imaging camera to search for any heat source,discovered no evidence of a fire.
A Waitrose spokeswoman said the store was evacuated for about half an hour before it was re-opened.
A total of seven appliances and a small fires unit are providing cover across the city and county until 10pm when the latest in a series of strikes by firefighters comes to an end.
A second four-hour stoppage is scheduled between 6pm and 10pm tomorrow.
