Police have arrested a 25-year-old man in relation to the assault of two people on Riverslea Rd earlier this month.
The second arrest comes after a 33-year-old man was remanded in custody last week.
No one else is being sought in relation to the attack.
Detective Sergeant Darren Pritchard said the two victims required hospital treatment and will make slow recoveries from their injuries.
"We have had tremendous support from the public, which we are very grateful for, and we continue to ask that anyone with additional information come forward to local Police or Crimestoppers (0800 555 111)," he said.
