Alfrid is only indirectly referred as one of the Masters Counselors but not by name. The character is created for the movies

The Hobbit: The Desolation of Smaug
Alfrid advises the Master in matters of diplomacy, trade and the defense of Lake-town. At heart though, he is a power-hungry sycophant, and his counsel could not always be relied upon to serve anyone other than himself.

He treats the citizens like dirt and stops Bard from entering Lake-Town with barrels filled with fish as he is not allowed to fill the barrells. He orders Braga and the guards to throw the fish into the lake, but Bard threatens to tell the citizens that the Master is throwing fish and Alfrid order the guards to stop and angrily allow him to pass.

Later on, Alfrid warns the Master about Bard's rebellious attitude against him, and is ordered to send spies to watch his house. He writes a fabricated excuse to arrest Bard. Later he was distrutful towards Thorin, Bilbo and the other Dwarves but eventually agrees with the greedy Master in welcoming them as friends. However the next day he rudely sends away Oin, Bofur, Fili and Kili refusing to help them.

Alfrid helps the guards by tripping Bard with the assistance of the Master knocking him unconscious with a stick to finish him off.

The Hobbit: The Battle of the Five Armies
Later Smaug attacks Esgaroth and he tries to escape with his gold, Alfrid, Braga and a few guards. However the boat was too slow and full of gold. The Master betrays Alfrid and throws him out into the lake and Bard uses his boat to free himself. When Smaug is killed by Bard his dead body falls on the boat, crushing the Master, Braga and the other guards.

Alfrid survives and continues to mistreat the Lakemen and behaves selfishly. He quickly takes side with Bard after the Master's death. When the Azog's army arrives, Alfrid flees after taking gold with him.
