A 17-year-old was attacked at the World’s End Estate on Friday evening at around six.
Less than 30 minutes earlier, police had been called to Tynemouth Street where a 14-year-old had been stabbed.
Both were initially described as having life threatening injuries, but these were downgraded in hospital to non-life-threatening.
It’s not confirmed the incidents are related.
