(Reuters) - British asset manager Woodford Investment Management Ltd disclosed a less than 5% stake in Circassia Pharmaceuticals Plc as of Sept. 13, a filing showed on Monday.

Woodford earlier held a 19.95% stake in the speciality biopharmaceutical company, according to the filing.

Woodford Investment Management has been under pressure from lawmakers and investors for not being able to meet redemption requests, after the flagship equity income fund was frozen in June.
