A 53-year-old man has appeared in court accused of blackmail.
Michael Feeney, of Ervey Road, faces a further charge of witness intimidation.
The charges relate to alleged incidents between November 2014 and January this year.
An investigating officer told Derry Magistrates Court he believed he could connect Feeney to the charges.
The 53-year-old was released on bail to appear in court again on March 23.
As part of his bail conditions, Feeney is banned from contacting the alleged injured parties and from entering the Maydown Road area.
