We report optical polarimetric observations of the blazar PG 1553+113 gathered during a period of intense gamma-ray emission detected by the MAGIC experiment (Atel #4069). The polarimetric observations were carried out using the RINGO2 polarimeter (Steele et al. 2010) in the Liverpool Telescope in La Palma, Canary Islands.
