A man has been arrested following reports of students being suspiciously approached in Christchurch

Police responded to concerns in Merivale and St Albans earlier this month so sent a letter to eleven schools warning of the suspicious behaviour.

It's reported the man was on a bike and allegedly stopping students and offering cash for inappropriate favours.

The 53-year-old man is due to appear in the Christchurch District Court today on charges of breaching release conditions.
