Sub Query Returning More Than One Row

I have the following query.

select top 3 dbo.oncd_incident.open_date,dbo.onca_product.description,dbo.onca_user.full_name,dbo.oncd_incident.incident_id,email, dbo.oncd_contact.first_name,dbo.oncd_contact.last_name,dbo.oncd_contact.contact_id

from dbo.oncd_incident

inner join dbo.oncd_incident_contact on dbo.oncd_incident_contact.incident_id=dbo.oncd_incident.incident_id

inner join dbo.oncd_contact on dbo.oncd_contact.contact_id=dbo.oncd_incident_contact.contact_id

inner join dbo.oncd_contact_email on dbo.oncd_contact_email.contact_id=dbo.oncd_contact.contact_id

inner join dbo.onca_user on dbo.oncd_incident.assigned_to_user_code=dbo.onca_user.user_code

inner join dbo.onca_product on dbo.onca_product.product_code=dbo.oncd_incident.product_code

where dbo.oncd_incident.incident_status_code='CLOSED'

and email is not null

and dbo.oncd_incident.open_date>DateAdd(wk,-2,getdate()) and dbo.oncd_incident.completion_date>=DateAdd(dd,-2,getdate()) and

dbo.oncd_incident.assigned_to_user_code in (select user_code from dbo.onca_user)

order by newid()

I want the query to be executed for each row returned by the sub query.If I use IN keyword it returns top 3 rows for any 3 of the users.But I want top 3 rows to be returned for each of teh user.Please help.
