Yet another attack has taken place at Piccadilly Gardens this afternoon.
Police and paramedics were shown rushing to the area shortly after midday on Monday, with several by-passers capturing the footage and posting it online.
Here's what we know about the incident so far.
Here at Piccadilly Gardens with @patkarney and Cllr Sam Wheeler. Have just been briefed by @GMPCityCentre about this targeted attack. As usual, thank you for the rapid response from GMP and other services. This is a targeted attack.— Cllr Jon-Connor Lyons ? (@JonConnorLyons) February 10, 2020
Reports suggest that a father and son were the victims of a knife attack on the corner of Oldham Street outside Morrisons.
Greater Manchester Police believe the assault to be a "targeted attack."
Eyewitnesses have stated there were as many as "five or six people" involved, and that the assailants - wearing hoods - escaped up Oldham Street towards Northern Quarter following the attack.

The decline of Piccadilly Gardens and surrounding streets is a scandal. Incidents almost every day. How far from being a no go zone? Action needed urgently @AndyBurnhamGM— Stephen O'Neill (@ste_owey) February 10, 2020
Bus services have been disrupted due to road closures, and one nearby company shut their doors and kept staff inside until the surrounding area was deemed safe.
Forensics have visited the scene.
This stabbing marks the fourth violent attack in Piccadilly Gardens in the space of a month, and Twitter is inundated with messages demanding action from Greater Manchester Mayor Andy Burnham.
