A 53-year-old Brierfield man has been arrested on suspicion of downloading indecent images of children.
A 56-year-old man from Burnley and two other men were also arrested this morning accused of similar offences.
They are currently in police custody and will be questioned by detectives throughout the day.
Police arrested 18 men from across the county earlier in the week as they continued a week-long crackdown on the sexual exploitation of children in Lancashire. All 18 men have been released on police bail pending further inquiries.
Det. Supt Neil Esseen, who heads up Lancashire Constabulary’s Public Protection Unit, said: “We have executed 20 search warrants around the county which has resulted in the arrest of 22 people who we believe have been involved in receiving and distributing sexual images of children.
“The operation has clearly demonstrated our ability and intention to tackle this issue. The public quite rightly expects us to protect children from being exploited and that is exactly what we will continue to deliver.”
Activities have included multi-agency briefings to staff at bus and railway stations, leisure centres and care homes; visits to local schools providing information packs and access to CEOP online training and visits to key locations where young people are potentially at risk of grooming or exploitation.
