Arrest warrants were issued for William Dwayne McDonald, 25, and Samater Ali, 26.
Police said that in a warrant execution there is an "elevated potential for violence and/or weapons to be present, members of the Emergency Response Unit were utilized."
Once it was determined there was no threat to the public, police re-opened Cecilia Avenue about 4:30 p.m.
Neither William McDonald or Samater Ali have been arrested in relation to this investigation and police continue their search.
Police also say there is an additional investigation related to Sunday's warrant and no further information will be provided at this time.
