Angry crowd storms McDonald's: 'We want szechuan sauce'

Police were called to some McDonald's restaurants on Saturday after a PR stunt to bring back a rare sauce backfired.

In 1998, McDonald's did a promotional campaign for Disney's Mulan that included a new Szechuan sauce for Chicken McNuggets. It became well known after featuring in the popular cartoon Rick and Morty.

On Saturday select McDonald's locations across the United States gave away Szechuan Sauce, in response to an avalanche of demands from fans of the Adult Swim cartoon.

But demand for the sauce far exceeded the supply.

In one video, police can be seen holding back people chanting "we want sauce".

Officers also attended other stores because hundreds of people turned up.

McDonald's apologised to fans on social media but repeated their warning that the release was going to be "super limited".
