Querying list items of document libraries returns incorrect values.

Question

I have several document libraries. I am trying to get only the documents that the a selected user has however it is returning other authors documents. Attached is my code. Any help would be greatly appreciated.
CamlQuery camlQuery = new CamlQuery();
string query = "<View Scope='Recursive' /><ViewFields><FieldRef Name='File' /><FieldRef Name='FileLeafRef' /><FieldRef Name='LinkFilename'/><FieldRef Name='LinkFilenameNoMenu' /><FieldRef Name='Modified' /><FieldRef Name='Created' /><FieldRef Name='Author' /></ViewFields>" + "<Where><Eq><FieldRef Name='Author' LookupId='TRUE'/><Value Type='Integer'>" + user.Id + "</Value></Eq><AND><Eq><FieldRef Name='ContentType' /><Value Type='Computed'>File</Value></Eq></And></Where>" +
"<OrderBy><FieldRef Name='Created' /><FieldRef Name='Modified' /></OrderBy><QueryOptions><RowLimit>" + count + "</RowLimit></QueryOptions></View>";
camlQuery.ViewXml = query;
listItems = list.GetItems(camlQuery);
clientContext.Load(listItems);
clientContext.ExecuteQuery();

Hi,                                                             
The CAML statement below can filter the documents created by a specific user,
 please test it in your environment：
@"<View Scope='RecursiveAll'>
<Query>
<Where>
<Eq>
<FieldRef Name='Author' />
<Value Type='User'>Display Name</Value>
</Eq>
</Where>
</Query>
<ViewFields>
<FieldRef Name='FileLeafRef' />
<FieldRef Name='Author' />
</ViewFields>
</View>";
