Season 2
Polliver is a Lannister Man-at-Arms under the command of Ser Amory Lorch. He accompanies Lorch in the attack on Yoren and his Night's Watch recruits. He knocks Arya Stark over when she runs to join the affray and takes Needle] from her. When the Lannister forces are victorious they take the survivors prisoner.

In the books
In the Song of Ice and Fire novels, Polliver is a Lannister Man-at-Arms but he is under the command of Ser Gregor Clegane instead of Ser Amory Lorch. In the books it is Lorch who leads the attack on Yoren's recruits but Arya, Gendry, Hot Pie and Lommy escape. They are captured later by Clegane's men and Lommy is killed by Raff the Sweetling rather than Polliver.
