Tractors have blocked the entrance of supermarkets in Co Londonderry town as farmers staged a protest over the dairy farming crisis in Northern Ireland.
Police said they were aware of protests at two supermarkets in Coleraine on Thursday evening.
A spokesman said tractors were used to partially block entrances and exits at both locations.
Officers attended the scene of the protests but no arrests were made.
Just hours earlier a convoy of tractors lined the grounds of Stormont as farmers staged a protest while an emergency committee meeting was held to discuss the crisis.
A meeting of the Stormont agriculture committee was recalled early.
In a bid to tackle the problem agriculture minister Michelle O'Neill has called for intervention at European level.
Dairy farmers have warned they will go out of business if they do not receive higher prices for their milk.
Farmers protested in the ground of Stormont over prices which are currently down to as little as 19p per litre.
This is significantly lower than the 28p that the Department of Agriculture and Rural Development (DARD) calculate is needed to cover the cost of production.
Arriving at Stormont on Thursday the farmers said they needed help quickly.
