Bobbi Kristina Brown: Aunt leaves funeral after outburst

The memorial for Whitney Houston's daughter Bobbi Kristina Brown has been marred by an outburst that reflects the continuing tensions in the family.

Bobbi Kristina's aunt, Leolah Brown, left the service after venting her anger at the role of another relative, Pat Houston - Whitney Houston's sister-in-law and former manager.

Speaking to media outside the church, Ms Brown, the sister of Bobbi Kristina's father R&B singer Bobby Brown, explained why she was angry.
