However, the LAPD officers who attended the callout said they saw no signs of broken glass or other items and no sign of "bruises, swellings or signs of injury" to Heard's face.
The documents are understood to be central to a defamation case that Depp has brought against Britain's The Sun newspaper after the publication ran a story labeling the actor a "wife-beater".
Depp has repeatedly denied abusing his former wife, while his lawyers claim Heard has "severely injured" Depp and "faked" abuse allegation.
Last year, in response to an opinion piece Heard wrote for the Washington Post, titled 'I spoke up against sexual violence – and faced our culture's wrath,' Depp's lawyer accused Heard of abusing the #metoo movement and said she "masquerades as a victim rather than abuser".
According to The Hollywood Reporter, Heard has asked to testify at the upcoming defamation trial but Depp's legal team has threatened to sue her for breaching her non-disclosure agreement if she does.
Heard's testimony is critical to the trial as The Sun battles to prove their headline was true.
The hearing is set down for February 22.
