Burger fans on the hunt for a free lunchtime treat ended up getting lost in an office block after a fire drill.

Deliveroo gave away free burgers from Solita in the Northern Quarter today to celebrate its fourth birthday.

However, organisers hit a snag when Manchester council asked them to move the giveaway from St Peter's Square to Stevenson Square in the Northern Quarter just an hour before it was due to start.

Crowds of burger fans instead had to make their way across the city just in time for their free burger.

Though the burgers ran out within ten minutes, Deliveroo employees promised they would be back at 2pm with more.

A number of dedicated burger lovers waited - but during that time neighbouring office Sevendale House had a fire drill.

Some of those waiting thought the fire drill was part of the crowd waiting for free burgers and followed them back into the office.

One man said: "We just kept following them into the office, we got led through the back entrance and climbed the stairs."

"I think we got to the fifth floor before somebody found us and realised we weren't meant to be there."

One of the building's managers confirmed they found about ten stragglers lost in the office still in search of the burgers after the fire drill had calmed down.

Josh waited in St Peter's Square until 1:15pm when he checked twitter and realised they weren't there, then waited in Stevenson Square until 2pm where he finally got his free food.

He said: "This is the best day."

Liam, Daniel and Dylan originally waited in St Peter's Square for the free food and saw on soical media that it had moved.

Liam said: "I don't want to admit to running here, but we had to get a shift on."

In Bristol last week when Deliveroo gave out free burgers, crowds pushed and shoved each other to get the free food.

However in Manchester the crowds queued politely and bar the confusion of the fire drill, everyone got their burgers smoothly.
