c) Immediately the E1 link was established, ETKL received TAP files from their
roaming partners in Dubai claiming Kshs 753,844.66 for roaming calls between
1st and 3rd November 2009;
d) That the number that originated the roaming call in Dubai was seen in the VLR
in Kenya 2 hours before it allegedly made the call in Dubai as a roaming
number. Therefore the number could not have physically roamed into a Dubai
network which is at least 4 hours flight away;
e) That the numbers are ordinary ETKL’s subscriber numbers not attributable to
ACL;
f) That the details of the roaming calls were not seen in any part of ETKL’s
systems or their international carriers including the E1 link between them and
ACL;
g) That pre-paid ETKL subscribers are barred from roaming and therefore no
roaming bills were expected from roaming partners in this regard. That for this
to have occurred, there was fraudulent activity being carried out in their
network;
h) That once the fraudulent activity was noticed, ACL was identified as the newest
entrant in ETKL’s network and that they could have been the source of the
fraud. A decision was then taken to disconnect the E1 link after which the
alleged fraudulent activity stopped;
i) That ACL used the link for the fraudulent activities that cost ETKL a loss of
Kshs753,844.66 in three days;
j) The suspected practice of call back scenario given through ETKL’s written
Submissions of 6th January 2009 was articulated as follows:

This call generates a TAP file payable by ETKL;
Through the internet, the call gets terminated in ACL Kenya; and
ACL Kenya delivers the call to ETKL through E1 connection.
