Remembered this thread earlier when someone from Lewisham Police Station called at the door and thought it was worth updating.

The investigation is ongoing (apparently practically every door in HOP and FH has been knocked). They've just got to the area north of Brockley Rise. There's a reward for information - the culprit is still attacking people. See the BBC news website for more information.

I'm quite impressed that the police continue to pursue this guy. Answering the question above, the burglaries/attacks are not happening in FH/HOP - but the perpetrator is returning to the area afterwards (not sure how the police know that).
