An arrest in Fayette County, Pennsylvania must be legally preceded by an arrest warrant. For an arrest warrant in Fayette County to be considered a valid one, a local sitting judge here needs to initially sign the warrant. Once this occurs, the warrant turns into an active warrant. In order words, the individual against whom the arrest warrant is issued will be searched by the police and consequently becomes liable for arrest the moment he is found.
