NSMutable array removeAllObject removing objects in other NSMutable array too

I have three class namely DepartmentViewController, DepartmentRequest, Department. Its like im making a department request from DepartmentViewcontroller and based on response im manipulating repsonse and adding in NSmutableArray *responseArray in DepartmentRequest class. This array just contains Department object. I want this responseArray in DepartmentViewController for searching and reloading tableview. so i passed this array to DepartmentViewController through delegate and assigning responseArray to localArray. Now I did searching based on these two array but if i remove any one of the array using removeallobject. Its removing object in other Array too.

if(searchString.length>0)
  {

      [localArray removeAllObjects];
    for (int i =0 ; i < [departmentRequest.responseArray count]; i++) {
      Department *dept = [departmentRequest.responseArray objectAtIndex:i];

        if (([dept.departmentName rangeOfString:searchString options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch)].location != NSNotFound)
          )

        {
                   [localArray addObject:dept];
        }
        else{
            NSLog(@"deptname %@",dept.departmentName);
        }

    }

    [departmentTableView reloadData];

if i remove object in localArray its removing objects both in departmentReqeust.responseArray and localArray

if(searchString.length>0) {

 // [localArray removeAllObjects];

 NSMutableArray arrTemp=[[NSMutableArray alloc]init];

for (int i =0 ; i < [departmentRequest.responseArray count]; i++) {
  Department *dept = [departmentRequest.responseArray objectAtIndex:i];

    if (([dept.departmentName rangeOfString:searchString options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch)].location != NSNotFound)
      )

    {
               [arrTemp addObject:dept];
    }
    else{
        NSLog(@"deptname %@",dept.departmentName);
    }

}
localArray = [NSArray arrayWithArray:arrTemp];

[departmentTableView reloadData];

You should assign like

localArray = [NSArray arrayWithArray:responseArray];
